Bourgin-Yang versions of the Borsuk-Ulam theorem for $p$-toral groups [PDF]
, 2016 Let $V$ and $W$ be orthogonal representations of $G$ with $V^G= W^G=\{0\}$. Let $S(V )$ be the sphere of $V$ and $f : S(V ) \to W$ be a $G$-equivariant mapping. We give an estimate for the dimension of the set $Z_f=f^{-1}\{0\}$ in terms of $ \dim V$ and $

Spectrum of equivariant cohomology as a fixed point scheme [PDF]
Épijournal de Géométrie AlgébriqueAn action of a complex reductive group $\mathrm G$ on a smooth projective variety $X$ is regular when all regular unipotent elements in $\mathrm G$ act with finitely many fixed points.

Steenrod squares on conjugation spaces [PDF]
, 2005 We prove that the coefficients of the so-called conjugation equation for conjugation spaces in the sense of Hausmann-Holm-Puppe are completely determined by Steenrod squares. This generalises a result of V.A.

Reflexive and dihedral (co)homology of a pre‐additive category
International Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 7, Page 429-438, 2001., 2001 The group dihedral homology of an algebra over a field with characteristic zero was introduced by Tsygan (1983). The dihedral homology and cohomology of an algebra with involution over commutative ring with identity, associated with the small category, were studied by Krasauskas et al. (1988), Loday (1987), and Lodder (1993).

Graded geometry in gauge theories and beyond [PDF]
, 2014 We study some graded geometric constructions appearing naturally in the context of gauge theories. Inspired by a known relation of gauging with equivariant cohomology we generalize the latter notion to the case of arbitrary Q-manifolds introducing thus ...

The relative dihedral homology of involutive algebras
International Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 4, Page 807-815, 1999., 1999 Let f : A → B be a homomorphism of involutive algebras A, B. The purpose of this paper is to define a free involutive algebra resolution of algebra B over f and use it to define and study the relative dihedral homology.

Adams and Steenrod operators in dihedral homology
International Journal of Mathematics and Mathematical Sciences, Volume 21, Issue 2, Page 341-346, 1998., 1996 In this article, we define the Adam′s and Steenrod′s operators in the dihedral homology.

The weighted Laplacians on real and complex metric measure spaces
, 2014 In this short note we compare the weighted Laplacians on real and complex (K\"ahler) metric measure spaces. In the compact case K\"ahler metric measure spaces are considered on Fano manifolds for the study of K\"ahler-Einstein metrics while real metric ...

Infinite flags and Schubert polynomials
Forum of Mathematics, SigmaWe study Schubert polynomials using geometry of infinite-dimensional flag varieties and degeneracy loci. Applications include Graham-positivity of coefficients appearing in equivariant coproduct formulas and expansions of back-stable and enriched ...

Interactions of strings and equivariant homology theories
, 2009 We introduce the notion of the space of parallel strings with partially summable labels, which can be viewed as a geometrically constructed group completion of the space of particles with labels.
