(1998)The objective of this thesis is to generalize this result to a bigger class of elliptic curves. We are going to generalize Serf's result to the family of elliptic curves with full 2torsion, i.e. elliptic curves of the ...

(2006)We consider the problem of constructing K3fibered and elliptically fibered CalabiYau threefolds over P1 and P2 respectively. We first show how to write weighted projective space bundles as toric varieties. We then ...

(1996)Infinitely representable functions are introduced, and it is proved that the expansion $\IR\sb{\cal G}$ of the field of reals by a certain subfamily of all infinitely representable functions (namely, the family of socalled ...

(1992)This paper deals with finite groups, and has two parts. In part I J. L. Brenner and James Wielgold (I,3) defined a finite nonabelian group G as lying in $\Gamma\sb1\sp{(2)}$ (spread onetwo) if for every 1 $\not=$ x $\in$ ...

(1984)Let [Special characters omitted.] be a stochastic sequence and let [Special characters omitted.] be a predictable sequence. Define S(,n) for each n by S(,n) = X(,0) + X(,1)V(,1) + ... + V(,n)X(,n). Let [Special characters ...

(2008)The Friendship Theorem states that if G is a graph in which every two vertices have exactly one common neighbor, then G has a dominating vertex. Sos defined an analogous friendship property for 3uniform hypergraphs, and ...

(1999)In Chapter 1 a Lefschetztype coincidence theorem for two maps from an arbitrary topological space to a manifold is given: the coincidence index is equal to the Lefschetz number. It follows that if the Lefschetz number of ...

(2009)A folded symplectic form on an evendimensional manifold is a closed twoform that degenerates in a suitably controlled way along a smooth hypersurface. When a torus having half the dimension of the manifold acts in a way ...

(1996)With regards to certain complete Riemannian manifolds we show that the analytic assembly map is rationally injective by using the exotic index theorem. The foliation exotic index theorem of S. Hurder is an extension of the ...

(20120918)We study problems in extremal combinatorics with respect to forbidden induced subgraphs, forbidden colored subgraphs, and forbidden subgraphs. In Chapter 2, we determine exactly which graphs H have the property that ...
