L–betti Numbers of Hypersurface Complements
نویسنده
چکیده
In [DJL07] it was shown that if A is an affine hyperplane arrangement in Cn, then at most one of the L2–Betti numbers b i (C n \ A, id) is non–zero. In this note we prove an analogous statement for complements of complex affine hypersurfaces in general position at infinity. Furthermore, we recast and extend to this higher-dimensional setting results of [FLM09, LM06] about L2–Betti numbers of plane curve complements.

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...
متن کاملAsymptotically Maximal Families of Hypersurfaces in Toric Varieties
A real algebraic variety is maximal (with respect to the SmithThom inequality) if the sum of the Betti numbers (with Z2 coefficients) of the real part of the variety is equal to the sum of Betti numbers of its complex part. We prove that there exist polytopes that are not Newton polytopes of any maximal hypersurface in the corresponding toric variety. On the other hand we show that for any poly...
متن کاملWhat is the total Betti number of a random real hypersurface?
We bound from above the expected total Betti number of a high degree random real hypersurface in a smooth real projective manifold. This upper bound is deduced from the equirepartition of critical points of a real Lefschetz pencil restricted to the complex domain of such a random hypersurface, equirepartition which we first establish. Our proofs involve Hörmander’s theory of peak sections as we...
متن کاملOn a special class of Stanley-Reisner ideals
For an $n$-gon with vertices at points $1,2,cdots,n$, the Betti numbers of its suspension, the simplicial complex that involves two more vertices $n+1$ and $n+2$, is known. In this paper, with a constructive and simple proof, wegeneralize this result to find the minimal free resolution and Betti numbers of the $S$-module $S/I$ where $S=K[x_{1},cdots, x_{n}]$ and $I$ is the associated ideal to ...
متن کاملSome cyclic covers of complements of arrangements
Motivated by the Milnor fiber of a central arrangement, we study the cohomology of a family of cyclic covers of the complement of an arbitrary arrangement. We give an explicit proof of the polynomial periodicity of the Betti numbers of the members of this family of cyclic covers.
