A Study of the Spectral Sequence for Locally Free Isometric Actions of Abelian Lie Groups
We give an upper bound on the number of the page on which the spectral sequence corresponding to a locally free isometric action of an abelian Lie group degenerates. We give examples showing that these bounds are indeed sharp. Finally, we further justify the study of this sequence by exhibiting a potential application to the study of harmonic forms.

Dismantling the sawmill motor to investigate an ignition failure. Changing the spark plug didn't help. It could be the HT lead but my local small engine guru says probably the coil.
Getting to the coil requires dismantling a whole lot of stuff...

Scientists say your “mind” isn’t confined to your brain, or even your body
You might wonder, at some point today, what’s going on in another person’s mind. You may compliment someone’s great mind, or say they are out of their mind. You may even try to expand or free your own mind.

Isometric-Universal Graphs for Trees
We consider the problem of finding the smallest graph that contains two input trees each with at most $n$ vertices preserving their distances. In other words, we look for an isometric-universal graph with the minimum number of vertices for two given trees. We prove that this problem can be solved in time $O(n^{5/2}\log{n})$. We extend this result to forests instead of trees, and propose an algorithm with running time $O(n^{7/2}\log{n})$. As a key ingredient, we show that a smallest isometric-un…

Formal derivation of an isentropic two-phase flow model from the multi-species Boltzmann equation
Starting from the multi-species Boltzmann equation for a gas mixture, we propose the formal derivation of the isentropic two-phase flow model introduced in [Romenski, E., and Toro, E. F., Comput. Fluid Dyn. J., 13 (2004)]. We examine the asymptotic limit as the Knudsen numbers approach zero, in a regime characterized by resonant intra-species collisions, where interactions between particles of the same species dominate. This specific regime leads to a multi-velocity and multi-pressure hydrodyna…

An isometry theorem induced by the Radon transform between the convolution and interleaving distances
One-parameter persistence modules are applied to various subjects as tools in data analysis. On the other hand, since the theoretical study of multi-parameter persistence modules is not enough and in progress, they have few applications. The sheaf theory is expected to elucidate detailed properties of persistence modules and give features of multi-parameter ones for applications. However, the categories of sheaves on two or more dimensional Euclidean spaces have more complicated structures than…

On Wednesday,
the Washington Post
named the Economist’s Washington correspondent
Adam O’Neal as its next opinion editor.
In his announcement on Twitter, O’Neal parroted his new boss’ words from last February almost verbatim,
telling Post readers in a chummy front-facing camera announcement that:
[Washington Post opinion page writers and editors are] going to be stalwart advocates of free markets and personal liberties.
We’ll be unapologetically patri…

New Washington Post Opinion editor claims explicitly right-wing revamp isn’t ‘Ideological’
A breakdown of Bezos’ final coup and the bizarre pathology of right-wing ideologues really, really wanting you not to think they’re ideological.
