High-corank torsion in homotopy of unitary groups via topological modular forms and higher real -theories
Hood Chatham, Yang Hu, Morgan Opie
Work of Toda identifies groups of metastable vector bundles on even-dimensional spheres with stable homotopy groups of certain stunted projective spectra. Using Weiss' unitary calc…
Realization of some Stanley-Reisner algebras and graph colorings
Yang Hu, Donald Stanley
It is a classical problem in algebraic topology to decide whether a given graded -algebra can be realized as the cohomology ring of a space. In this paper, we introduce…
Deformed Aeppli cohomology: canonical deformations and jumping formulas
Yan Hu, Wei Xia
Given a complex analytic family of complex manifolds, we consider canonical Aeppli deformations of -forms and study its relations to the varying of dimension of the deformed…
Characterization of polynomials by their invariance properties
J. M. Amira, Ya-Qing Hu
We prove that certain classical groups serve to characterize ordinary polynomials in real variables as elements of finite-dimensional subs…
