On Normal Subgroups of Coxeter Groups Generated by Standard Parabolic Subgroups
Swiatoslaw R. Gal
We discuss one construction of nonstandard subgroups in the category of Coxeter groups. Two formulae for the growth series of such a subgroups are given. As an application we const…

Real Root Conjecture fails for five and higher dimensional spheres
Swiatoslaw R. Gal
A construction of convex flag triangulations of five and higher dimensional spheres, whose h-polynomials fail to have only real roots, is given. We show that there is no such examp…
