We determine rank numbers for the prism graph P 2 ×C n (P 2 being the connected two-node graph and C n a cycle of length n) and for the square of an even cycle.
Recall that algebraic sets are characterized by resolution tower structures [AK1], [AK2]. A topological space with such a structure is called a TR space for short. In low dimensions existence of resolution tower structures can often be detected by combinatorial invariants of the underlying topological spaces. For example, let X be a locally cone-like Euler… (More)
We discuss elementary properties of strongly algebraic vector bundles, and give a proof that the classifying map of such bundles to Grass-mann variety could be algebraically deformed to an algebraic imbedding.
