Query: On topological aspects of 2D graphene like materials   We study the graphene lattice with a curvature effect. The action depicting
multilayers of graphene is portrayed in curved spacetime and effective Dirac
equation scopes the curvature effect. The magnetic field is responsible for the
geometric variations and these changes are identified as topological aspects in
graphene. By varying the geometry of the graphene one can create topologically
distinct surfaces which could be remarked as torus or sphere. The 2D hexagonal
tessellation induces a curvature effect and the tessellation plane is reduced
to a 2-torus having genus g=1.
