Rough ideals based on ideal determined varieties

The paper is devoted to concern a relationship between rough set theory and universal algebra. Notions of lower and upper rough approximations on an algebraic structure induced by an ideal are introduced and some of their properties are studied. Also, notions of rough subalgebras and rough ideals with respect to an ideal of an algebraic structure, which is an extended notion of subalgebras and ...

The Topological Invariants of Algebraic Varieties

1. Since the origins of the birational geometry of algebraic varieties cai be traced back to Riemann's theory of algebraic functions, it is not surprising that topological considerations have played a considerable role in the theory of algebraic varieties defined over the field of complex numbers. For instance in the theory of algebraic functions of two complex variables, due mainly tc Picard, ...

Thomason’s Theorem for Varieties over Algebraically Closed Fields

We present a novel proof of Thomason’s theorem relating Bott inverted algebraic K-theory with finite coefficients and étale cohomology for smooth varieties over algebraically closed ground fields. Our proof involves first introducing a new theory, which we term algebraic K-homology, and proving it satisfies étale descent (with finite coefficients) on the category of normal, Cohen-Macaulay varie...

Betti number bounds for fewnomial hypersurfaces via stratified Morse theory

We use stratified Morse theory for a manifold with corners to give a new bound for the sum of the Betti numbers of a fewnomial hypersurface in RN> . In the book “Fewnomials” [6], A. Khovanskii gives bounds on the Betti numbers of varieties X in R or in the positive orthant R>. These varieties include algebraic varieties, varieties defined by polynomial functions in the variables and exponential...

Algebraic Cocycles on Normal, Quasi-Projective Varieties

Blaine Lawson and the author introduced algebraic cocycles on complex algebraic varieties in [FL-1] and established a duality theorem relating spaces of algebraic cocycles and spaces of algebraic cycles in [FL-2]. This theorem has non-trivial (and perhaps surprising) applications in several contexts. In particular, duality enables computations of “algebraic mapping spaces” consisting of algebra...
