Logarithmic prismatic cohomology II

T Koshikawa, Z Yao - arXiv preprint arXiv:2306.00364, 2023 - arxiv.org
We continue to study the logarithmic prismatic cohomology defined by the first author, and
complete the proof of the de Rham comparison and\'etale comparison generalizing those of …

[HTML][HTML] Diagram spaces and symmetric spectra

S Sagave, C Schlichtkrull - Advances in Mathematics, 2012 - Elsevier
We present a general homotopical analysis of structured diagram spaces and discuss the
relation to symmetric spectra. The main motivating examples are the I-spaces, which are …

This paper incorporates the theory of Hochschild homology into our program on log motives.
We discuss a geometric definition of logarithmic Hochschild homology of animated pre-log …

Topological modular forms with level structure

M Hill, T Lawson - Inventiones mathematicae, 2016 - Springer
The cohomology theory known as Tmf Tmf, for “topological modular forms,” is a universal
object mapping out to elliptic cohomology theories, and its coefficient ring is closely …

Derived -Geometry I: Foundations

P Steffens - arXiv preprint arXiv:2304.08671, 2023 - arxiv.org
This work is the first in a series laying the foundations of derived geometry in the $ C^{\infty}
$ setting, and providing tools for the construction and study of moduli spaces of solutions of …

Bökstedt periodicity and quotients of DVRs

A Krause, T Nikolaus - Compositio Mathematica, 2022 - cambridge.org
In this paper we compute the topological Hochschild homology of quotients of discrete
valuation rings (DVRs). Along the way we give a short argument for Bökstedt periodicity and …

Logarithmic prismatic cohomology via logarithmic THH

F Binda, T Lundemo, D Park… - International Mathematics …, 2023 - academic.oup.com
Abstract Inspired by Bhatt–Morrow–Scholze's work on, we define Nygaard-completed log

Logarithmic prismatic cohomology, motivic sheaves, and comparison theorems

F Binda, T Lundemo, A Merici, D Park - arXiv preprint arXiv:2312.13129, 2023 - arxiv.org
We prove that (logarithmic) prismatic and (logarithmic) syntomic cohomology are
representable in the category of logarithmic motives. As an application, we obtain Gysin …
