Abstract:Let h1(u),…, hk(u) be Laurent polynomials of m-variables and letbe a non-degenerate complete intersection variety. Such an intersection variety appears as an exceptional divisor of a resolution of non-degenerate complete intersection varieties with an isolated singularity at the origin (Ok4]).

Section: Motivic Milnor Fibers Over CI and Their Virtual Betti Polymentioning
We study the Jordan normal forms of the local and global monodromies over complete intersection subvarieties of C n by using the theory of motivic Milnor fibers. The results will be explicitly described by the mixed volumes of the faces of Newton polyhedrons.

Abstract. In this paper we compute the integral cohomology groups for all examples of Calabi-Yau 3-folds obtained from hypersurfaces in 4-dimensional Gorenstein toric Fano varieties. Among 473 800 776 families of Calabi-Yau 3-folds X corresponding to 4-dimensional reflexive polytopes there exist exactly 32 families having non-trivial torsion in H * (X, Z). We came to an interesting observation that the torsion subgroups in H 2 and H 3 are exchanged by the mirror symmetry involution.
“…in terms of the Newton polyhedra of the component functions of F. The class of non-degenerate maps is sufficiently large and plays an important role in Singularity Theory and Algebraic Geometry (see, for instance, [1], [21], [48]). We will apply this condition for real polynomial maps.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
