Free Action of Finite Groups on Spaces of Cohomology Type (0, b)

Somorjit K Singh, Hemant Kumar Singh, Tej Bahadur Singh

Let G be a finite group acting freely on a finitistic space X having cohomology type (0, b) (for example, S^n x S^{2n} is a space of type (0, 1) and the one-point union S^n V S^{2n…

Free actions of connected Lie groups of rank one on certain spaces

Hemant Kumar Singh, Jaspreet Kaur, Tej Bahadur Singh

Let be a connected Lie group of rank one. In this paper the existence of free actions of group on spheres, real projective spaces and lens spaces has been studied. Most of…

Cohomology algebra of the orbit space of some free actions on spaces of cohomology type (a, b)

Hemant Kumar Singh, Tej Bahadur Singh

Let X be a finitistic space with non-trivial cohomology groups H^in(X;Z)=Z with generators v_i, where i = 0, 1, 2, 3. We say that X has cohomology type (a, b) if v_1^2 = av_2 and v…

Cohomology algebra of the orbit space of free circle group actions on lens spaces

Hemant Kumar Singh, Tej Bahadur Singh

Suppose that G=S^1 acts freely on a finitistic space X whose mod p cohomology ring isomorphic to that of a lens space L^{2m-1}(p;q_1,...,q_m). In this paper, we determine the mod p…

On the cohomology of orbit space of free \pmb{${\ZZ}_{p}$}-actions on lens spaces

Hemant Kumar Singh, Tej Bahadur Singh

Let $G = \ZZ_p$, an odd prime, act freely on a finite-dimensional CW-complex with mod cohomology isomorphic to that of a lens space . In this…
