Uniqueness of A-infinity structures and Hochschild cohomology [PDF]
, 2011 Working over a commutative ground ring, we establish a Hochschild cohomology criterion for uniqueness of derived A-infinity algebra structures in the sense of Sagave.

Localization of Cohomological Induction
Publications of the Research Institute for Mathematical Sciences, 2013 We give a geometric realization of cohomologically induced (\mathfrak{g},K) -modules. Let (\mathfrak{h}, L) be a subpair of

Separating invariants and local cohomology [PDF]
Advances in Mathematics, 2015 The study of separating invariants is a recent trend in invariant theory. For a finite group acting linearly on a vector space, a separating set is a set of invariants whose elements separate the orbits of G. In some ways, separating sets often exhibit better behavior than generating sets for the ring of invariants.

International Journal of Mathematics and Mathematical Sciences, 2006 We discuss the calculation of integral cohomology ring of LG/T and ΩG. First we describe the root system and Weyl group of LG, then we give some homotopy equivalences on the loop groups and homogeneous spaces, and calculate the cohomology ring structures

Artinianness of formal local cohomology modules [PDF]
, 2011 summary:Let ${\frak{a}}$ be an ideal of Noetherian local ring $(R,{\frak{m}})$ and $M$ a finitely generated $R$-module of dimension $d$. In this paper we investigate the Artinianness of formal local cohomology modules under certain conditions on the ...

Cohomology of Homotopy Colimits of Simplicial Sets and Small Categories
Mathematics, 2020 This paper deals with well-known weak homotopy equivalences that relate homotopy colimits of small categories and simplicial sets. We show that these weak homotopy equivalences have stronger cohomology-preserving properties than for local coefficients.

Purely Coclosed G2‐Structures on Nilmanifolds—II
Mathematische Nachrichten, EarlyView.ABSTRACT This paper completes the classification of seven‐dimensional nilpotent Lie groups endowed with a left‐invariant purely coclosed G2$\text{G}_2$‐structure, initiated in Bazzoni et al. [Mathematische Nachrichten 296 no. 6 (2023): 2236–2257], the authors provided the classification of decomposable seven‐dimensional nilpotent Lie groups and of the ...
