Integral equivariant -theory and cobordism ring of simplicial GKM orbifold complexes

Koushik Brahma, Soumen Sarkar

In this paper, we define `simplicial GKM orbifold complexes' and study some of their topological properties. We introduce the concept of filtration of regular graphs and `simplicia…

LS-category and topological complexity of several families of fibre bundles

Navnath Daundkar, Soumen Sarkar

In this paper, we study upper bounds for the topological complexity of the total spaces of some classes of fibre bundles. We calculate a tight upper bound for the topological compl…

Use of a smartphone camera to determine the focal length of a thin lens by finding the transverse magnification of the virtual image of an object

Sanjoy Kumar Pal, Soumen Sarkar, Surajit Chakrabarti

In this work we have determined the focal length of a concave lens by photographing the virtual image of an object by a smartphone camera. We have similarly determined the focal le…

Relative LS categories and higher topological complexities of maps

Yuli B. Rudyak, Soumen Sarkar

In this paper, we study three relative LS categories of a map and study some of their properties. Then we introduce the `higher topological complexity' and `weak higher topological…

Maps of degree one, relative LS category and higher topological complexities

Yuli B. Rudyak, Soumen Sarkar

In this paper, we introduce relative LS category of a map and study some of its properties. Then we introduce `higher topological complexity' of a map, a homotopy invariant. We giv…

Triangulations of with few vertices

Soumen Sarkar

P. Arnoux and A. Marin showed that any triangulation of contains more than vertices if . We construct some natural triangulation of…
