The Mass Density of Merging Binary Black Holes Over Cosmic Time
The connection between the binary black hole (BBH) mergers observed by LIGO-Virgo-KAGRA (LVK) and their stellar progenitors remains uncertain. Specifically, the fraction $ε$ of stellar mass that ends up in BBH mergers and the delay time $τ$ between star formation and BBH merger carry information about the astrophysical processes that give rise to merging BBHs. We model the BBH merger rate in terms of the cosmic star formation history, coupled with a metallicity-dependent efficiency $ε$ and a…

Explicit open images for elliptic curves over $\mathbb{Q}$
For a non-CM elliptic curve $E$ defined over $\mathbb{Q}$, the Galois action on its torsion points gives rise to a Galois representation $ρ_E: Gal(\overline{\mathbb{Q}}/\mathbb{Q})\to GL_2(\widehat{\mathbb{Z}})$ that is unique up to isomorphism. A renowned theorem of Serre says that the image of $ρ_E$ is an open, and hence finite index, subgroup of $GL_2(\widehat{\mathbb{Z}})$. We describe an algorithm that computes the image of $ρ_E$ up to conjugacy in $GL_2(\widehat{\mathbb{Z}})$; this alg…

Consider the wave equation with heterogeneous coefficients in the homogenization regime. At large times, the wave interacts in a nontrivial way with the heterogeneities, giving rise to effective dispersive effects. The main achievement of the present work is a new ansatz for the long-time two-scale expansion inspired by spectral analysis. Based on this spectral ansatz, we extend and refine all previous results in the field, proving homogenization up to optimal timescales with optimal error esti…

Daily pic of Brisbane

I've been reading Ray Dailo's "Principles for dealing with the changing world order" in which he charts the rise and fall of empires and kingdoms and dynasties.
The main cycle, he reckons is:
1) Winner of a war consolidates power, unites the population (often through oppression)
2) A smart cooperative equitable educated society with meritocracy means good societal progress and wide sharing of the wealth.
3) Long period of peace, building good tech and military and financial systems.
4) Leadership corrupts: Excessive debt, money-printing, inequality, financial ruin, no sense of solidarity, then a natural disaster pushes it over the edge
5) The fall: Escalating rebellions, very bad inequality, internal conflicts
6) Civil war, revolution, eventually a strong leader proves the winner and back to 1.
We in the western civilization are very clearly in the late states of this kind of cycle, and it's frankly terrifying with the weapons we have these days when it comes to a war.
The leadership is too corrupt to try and fix the inequality or invest in that well educated, equitable, cooperative society.
He explicitly agrees with Marx and implicitly with me a lot more than I'd have expected from the rabid capitalist that Ray Dailo is.
It's interesting to hear his emphasis on inequality and how a prosperous society depends upon sharing the gains of prosperity widely. You tend to hear hyper-capitalists mostly emphasizing that capital's gains should go to capital, and Ray is certainly suggesting the opposite here. That if that happens, it corrupts the leadership and ends with cronyism and debt and revolution.
We seem to basically agree what creates good prosperous peaceful civil society, and that capitalism in the Anglican world isn't doing it, and that fucked up corrupt government is why we aren't doing it.
We'd offer fairly different prescriptions though I think.

A Universal Property of the Spectrum of a Ring and the Semiring of its Ideals
Arithmetic valuations are intimately connected with the structure of the ideals of a commutative ring. We show how the generalized idempotent semiring valuations of Jeffrey and Noah Giansiracusa can be used to make this connection explicit. Through this generalized valuation theory sufficiently complete positive valuations give rise to Galois correspondences with the lattice of ideals of a commutative ring. Up to isomorphism the semiring of ideals of a commutative ring can be defined as a unive…

Since it came up in another thread I thought it'd be useful to quote W.E.B. Du Bois on the American Dream. This is from Black Reconstruction in America:
"Behind this extraordinary industrial development, as justification in the minds of men, lay what we may call the great American Assumption, which up to the time of the Civil War, was held more or less explicitly by practically all Americans. The American Assumption was that wealth is mainly the result of its owner’s effort and that any average worker can by thrift become a capitalist. The curious thing about this assumption was that while it was not true, it was undoubtedly more nearly true in America from 1820 to 1860 than in any other contemporary land. It was not true and not recognized as true during Colonial times; but with the opening of the West and the expanding industry of the twenties, and coincident with the rise of the Cotton Kingdom, it was a fact that often a poor white man in America by thrift and saving could obtain land and capital; and by intelligence and good luck he could become a small capitalist and even a rich man; and conversely a careless spendthrift though rich might become a pauper, since hereditary safeguards for property had little legal sanction.
Thus arose the philosophy of “shirt-sleeves to shirt-sleeves,” on which the American theory of compensated democracy was built. It asked simply, in eighteenth century accents, freedom from government interference with individual ventures, and a voice in the selection of government officials. The continued freedom of economic opportunity and ever possible increase of industrial income, it took for granted. This attitude was back of the adoption of universal suffrage, the disappearance of compulsory military service and imprisonment for debt, which characterized Jacksonian democracy. The American Assumption was contemporary with the Cotton Kingdom, which was its most sinister contradiction. The new captains of industry in the North were largely risen from the laboring class and thus living proof of the ease of capitalistic accumulation. The validity of the American Assumption ceased with the Civil War, but its tradition lasted down to the day of the Great Depression, when it died with a great wail of despair, not so much from bread lines and soup kitchens, as from poor and thrifty bank depositors and small investors."

Searching for late-time interaction signatures in Type Ia supernovae from the Zwicky Transient Facility
The nature of the progenitor systems and explosion mechanisms that give rise to Type Ia supernovae (SNe Ia) are still debated. The interaction signature of circumstellar material (CSM) being swept up by expanding ejecta can constrain the type of system from which it was ejected. Most previous studies have focused on finding CSM ejected shortly before the SN Ia explosion still residing close to the explosion site, resulting in short delay times until the interaction starts. We use a sample of 36…
