Four - dimensional varieties of general type with the same Betti numbers as P 1 × P 1 × P 1 ×

چکیده
We give two examples of algebraic fourfolds of general type with the same Betti numbers as the product of projective lines ( P )4 . Both examples are realized as quotients Γ\H of the product H of four copies of the upper half plane H by irreducible discrete groups of automorphisms. 2000 Mathematics Subject Classification 11F06, 22E40

Remarks on the Combinatorial Intersection Cohomology of Fans
This partly expository paper reviews the theory of combinatorial intersection cohomology of fans developed by Barthel-Brasselet-Fieseler-Kaup, Bressler-Lunts, and Karu. This theory gives a substitute for the intersection cohomology of toric varieties which has all the expected formal properties but makes sense even for non-rational fans, which do not define a toric variety. As a result, a numbe...
متن کاملBetti 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...
متن کاملBounds on the individual Betti numbers of complex varieties, stability and algorithms
We prove graded bounds on the individual Betti numbers of affine and projective complex varieties. In particular, we give for each p, d, r, explicit bounds on the p-th Betti numbers of affine and projective subvarieties of Ck and PC, defined by r polynomials of degrees at most d as a function of p, d and r. Unlike previous bounds these bounds are independent of k, the dimension of the ambient s...
متن کاملt–ANALOGS OF q–CHARACTERS OF QUANTUM AFFINE ALGEBRAS OF TYPE
We compute t–analogs of q–characters of all l–fundamental representations of the quantum affine algebras of type E (1) 6 , E (1) 7 , E (1) 8 by a supercomputer. In particular, we prove the fermionic formula for Kirillov-Reshetikhin modules conjectured by Hatayama et al. [6] for these classes of representations. We also give explicitly the monomial realization of the crystal of the corresponding...
متن کاملCocompact Arithmetic Subgroups of Pu
We will say that a smooth projective complex algebraic variety V (of dimension n − 1) is a fake Pn−1 if V is the quotient of the unit ball Bn−1 by a torsion-free cocompact discrete subgroup of PU(n − 1, 1), and all the Betti numbers of V are equal to those of Pn−1 C . If the fundamental goup of a fake P n−1 is an arithmetic subgroup of PU(n − 1, 1), then we will say that it is an arithmetic fak...
