The homological spectrum for monoidal triangulated categories
The authors develop a notion of homological prime spectrum for an arbitrary monoidal triangulated category, ${\mathbf C}$. Unlike the symmetric case due to Balmer, the homological primes of ${\mathbf C}$ are not defined as the maximal Serre ideals of the small module category ${\sf mod}\text{-}{\mathbf C}$, or via a noncommutative ring theory inspired version of this construction. Instead, the authors work with an extended comparison map from the Serre prime spectrum $\operatorname{Spc} ({\sf m…

${\sf QMA}={\sf QMA}_1$ with an infinite counter
A long-standing open problem in quantum complexity theory is whether ${\sf QMA}$, the quantum analogue of ${\sf NP}$, is equal to ${\sf QMA}_1$, its one-sided error variant. We show that ${\sf QMA}={\sf QMA}^{\infty}= {\sf QMA}_1^{\infty}$, where ${\sf QMA}_1^\infty$ is like ${\sf QMA}_1$, but the verifier has an infinite register, as part of their witness system, in which they can efficiently perform a shift (increment) operation.

Nonconvex Optimization Framework for Group-Sparse Feedback Linear-Quadratic Optimal Control I: Penalty Approach
This paper develops a unified nonconvex optimization framework for the design of group-sparse feedback controllers in infinite-horizon linear-quadratic (LQ) problems. We address two prominent extensions of the classical LQ problem: the distributed LQ problem with fixed communication topology (DFT-LQ) and the sparse feedback LQ problem (SF-LQ), both of which are motivated by the need for scalable and structure-aware control in large-scale systems. Unlike existing approaches that rely on convex r…

We investigate refinements of the mean-payoff criterion in two-player zero-sum perfect-information stochastic games.

The notion of $d$-sensitive optimality interpolates between mean-payoff optimality (corresponding to the case $d=-1$) and Blackwell optimality ($d=+\infty$).

Sensitivity and transitivity for the induced maps on symmetric product suspensions of a topological space
Given a nondegenerate compact perfect and Hausdorff topological space $X$,$n\in \mathbb{N}$ and a function $f:X\rightarrow X$, we consider the $n$-fold symmetric product of $X$, $F_n(X)$ and the induced function $F_n(f):F_n(X)\rightarrow F_n(X)$. If $n\geq2$, we consider the $n$-fold symmetric product suspension of $X$, $SF_n(X)$ and the induced function$SF_n(f):SF_n(X)\rightarrow SF_n(X)$. In this paper, we study the relationships between the following statements: (1) $f\in \mathcal{M}$,(2) $F…

A language $L$ is said to be ${\cal C}$-measurable, where ${\cal C}$ is a class of languages, if there is an infinite sequence of languages in ${\cal C}$ that ``converges'' to $L$. We investigate the properties of ${\cal C}$-measurability in the cases where ${\cal C}$ is SF, the class of all star-free languages, and G, the class of all group languages. It is shown that a language $L$ is SF-measurable if and only if $L$ is GD-measurable, where GD is the class of all generalised definite language…

It happens every few generations.
It’s what drove the fascist oligarchs of the Confederacy to reach out and try to conquer the entire United States in the 1860s.

"tough on crime" ruins lives and doesn't make us safe.

A 19-year-old in S.F. treatment program passed some notes. Now, he faces years in prison.
SF aims to both get tougher on crime and put recovery first. How many second chances should a teenage defendant with addiction issues get?

The Evolutionary Path of Star-Forming Clumps in Hi-GAL
Star formation (SF) studies are benefiting from the huge amount of data made available by recent large-area Galactic plane surveys conducted between 2 μm and 3 mm. Fully characterizing SF demands integrating far-infrared/sub-millimetre (FIR/sub-mm) data, tracing the earliest phases, with near-/mid-infrared (NIR/MIR) observations, revealing later stages characterized by YSOs just before main sequence star appearance. However, the resulting dataset is often a complex mix of heterogeneous and int…

"Strada is seeking to use state housing laws that will both streamline approvals for the development and allow for denser construction — in exchange for the inclusion of affordable units.""
Yes, inclusion of affordable units at a lower rate than San Francisco's existing inclusionary requirements, and well below the level of induced demand per SF Planning's Residential Nexus studies. In other words, it creates even more stress in the affordable housing segment.…

SoMa housing plan ‘encouraging’ to boosters

The Jury Assembly room at SF Superior Court is a cell service black hole. At least they have wif---oh wait it acts like dial-up and screws with SSL certs? No thank you.

Mayor Danny Bluejeans' cruel crackdown on people experiencing homelessness in SF is... sending them instead to SFO. Displacement is not a solution. (But he's about to double down on displacement by banning RVs too) #sfpol

hope this will lead to lots of garages and driveways being eliminated!

S.F. passes law to let homeowners sell new in-law units as condos
The legislation aims to benefit "house-rich, cash-poor" homeowners, while adding to the city's supply of "affordable, entry-level" homes.

"the operations at the two new Laguna Street sites will be contracted out which means they will no longer be eligible to work with their clients."
Somehow, I get the feeling that the great minds behind this project fail to understand the importance of community and trust.

S.F. plans to move mentally ill adults draws protest
If the city has its way, all 83 residents will be moved to two facilities on Laguna Street in Hayes Valley.

SF folks: please call your supervisor and ask them not to redirect permanent affordable housing funds to temporary shelter
it’s likely illegal and it’s nonsense: the shelters would free up if people could exit to permanent housing!

San Francisco is About to Defund Solutions to Homelessness
After a late-night session on June 26, the Budget & Appropriations Committee of San Francisco’s Board of Supervisors is moving forward with a set of proposed resolutions regarding the budget. T…

All 5 SF YIMBY endorsed supervisors—Sauter, Engardio, Mahmood, Dorsey, and Melgar—voted to take $34 to $53 million away from building permanent affordable housing, *and* to ban RVs from all city streets.
So much for "legalize housing." With YIMBYs like this, who needs NIMBYs? #sfPol

What I really like to see is that 35% of visitors to Sunset Dunes Park are from adjacent neighborhoods! (That is a plurality, by the way.)

Mayor Lurie has to be reined in. He thinks he's CEO of the city and can do whatever he wants, and the Board of Supervisors keeps rolling over and letting him. Good on Kathrin Moore for this

oh sure SF Chronicle, blow up my spots
they cite as underrated parks: Holly Park, Ina Coolbrith Park, Corona Heights, Golden Gate Heights, Sutro Heights, Bayview Park, Visitacion Valley Greenway, Crane Cove Park, Glen Canyon Park.
I feel like Glen Canyon and Corona Heights are quite well known. strong picks otherwise

Situation: There are 13 different bike, transit, and safe streets advocacy groups in SF.
“13?! This is ridiculous! We should make a single group that covers everyone’s priorities!”

I didn't notice this in person but that's pretty funny https://www.sfgate.com/local/article/sf-street-signs-vandalized-allude-sex-work-20335773.php

SFMTA is adding left turns back to Valencia at 17th, 21st and 23rd streets with a new phase, which will cut down on time for pedestrian and bike crossings. The word is that Mayor Lurie directly ordered this. Signal modifications are very expensive and that money could have gone to safety or transit priority.
Seems small, but it's wasteful and adds to the "death by a thousand cuts" for Transit First in Lurie's SF.

No one wants to live on Van Ness because it's a loud car sewer. Condo listings with a Van Ness address will tell you in all-caps if the unit doesn't face Van Ness. There's also no green space there. It makes housing on the corridor a passing-through place rather than somewhere to set down roots.

Van Ness Is ‘In Crisis.’ Revival Plans Hinge On Housing Towers and Chain Stores
This main SF thoroughfare once had grand houses and auto palaces. Now there’s a great bus line, but empty storefronts. Can it again be a place to live and linger?

In Jason Henderson's 2013 book Street Fight he writes of SF transportation politics as a function of 3 factions: conservatives, neoliberals, progressives. How the street fights go depends on how those factions align. If you slot in YIMBYish urbanist types—those who are pro-bike, pro-business, believe that Dean Preston was blocking housing—as the neoliberals, this holds up surprisingly well today.

we should trick SF politicians by asking them which is their favorite Caltrain line

much smaller scale, but Mayor Lurie's SF budget increasing money for cops and jails while slashing social services (eviction legal aid, food bank, etc.) rhymes with the federal bill throwing people off Medicaid to fund concentration camps and ICE.

Looks like it wouldn’t be too hard for ICE to tap the Flock cameras increasingly deployed around SF, if they aren’t already, by asking either SFPD or other PDs it shares access with to do the searches for them
