On Reidemeister torsion of flag manifolds of compact semisimple Lie groups
AIMS Mathematics, 2020 In this paper we calculate Reidemeister torsion of flag manifold $K/T$ of compact semi-simple Lie group $K=SU_{n+1}$ using Reidemeister torsion formula and Schubert calculus, where $T$ is maximal torus of $K$. We find that this number is 1.

Irrational l2-invariants arising from the lamplighter group [PDF]
, 2015 We show that the Novikov-Shubin invariant of an element of the integral group ring of the lamplighter group Z_2 \wr Z can be irrational. This disproves a conjecture of Lott and Lueck.

On Integral INICS Aromaticity of Pyridodiazepine Constitutional Isomers and Tautomers
Molecules, 2023 The structure, energetics, and aromaticity of c.a. 100 constitutional isomers and tautomers of pyrido[m,n]diazepines (m = 1, 2; n = 2, 3, 4, 5; m ≠ n) were studied at the B3LYP/cc-pVTZ level.

A counterexample to the first Zassenhaus conjecture [PDF]
, 2017 Hans J. Zassenhaus conjectured that for any unit u of finite order in the integral group ring of a finite group G there exists a unit a in the rational group algebra of G such that a−1· u · a = ±g for some g ∈ G.

Integral group ring of the Mathieu simple groupM12 [PDF]
, 2006 We consider the Zassenhaus conjecture for the normalized unit group of the integral group ring of the Mathieu sporadic groupM12. As a consequence, we confirm for this group the Kimmerle’s conjecture on prime graphs.

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
