A distinguished subring of the Chow ring and cohomology of

Xing Gu

We determine a subring of the Chow ring and the cohomology of , the classifying space of the projective linear group of degree over complex numbers, and explain a way i…

On The Topological Period-Index Problem over 8-manifolds

Diarmuid Crowley, Xing Gu, Christian Haesemeyer

We establish upper bounds of the indices of topological Brauer classes over a closed orientable 8-manifolds. In particular, we verify the Topological Period-Index Conjecture (TPIC)…

The composition of R.~Cohen's elements and the third periodic elements in stable homotopy groups of spheres

Xing Gu, Xiangjun Wang, Jianqiu Wu

In this paper, we study the cohomology of the Morava stabilizer algebra . As an application, we show that for , if , $n\not \eq…

Some torsion classes in the Chow ring and cohomology of

Xing Gu

In the integral cohomology ring of the classifying space of the projective linear group (over ), we find a collection of -torsions of degree $2(p^{…

The Topological Period-Index Problem over 8-Complexes, II

Xing Gu

We complete the study of the topological period-index problem over 8 dimensional finite CW complexes started in a preceding paper. More precisely, we determine the sharp upper boun…
