In these notes a recently developed technique for the computation of line bundle-valued sheaf cohomology group dimensions on toric varieties is reviewed. The key result is a vanishing theorem for the contributing components which depends on the structure of the Stanley-Reisner ideal generators. A particular focus is placed on the (simplicial) Alexander duality that provides a central tool for the two known proofs of the algorithm. 
Physics inspired algorithms for (co)homology computation
This paper presents a physics inspired algorithm for first cohomology group computations on three-dimensional complexes that solves one of the most long-lasting problems in low-frequency computational electromagnetics.


Cohomology of line bundles: A computational algorithm
We present an algorithm for computing line bundle valued cohomology classes over toric varieties. This is the basic starting point for computing massless modes in both heterotic and type IIB/F-theory
Cohomology of Line Bundles: Proof of the Algorithm
We present a proof of the algorithm for computing line bundle valued cohomology classes over toric varieties conjectured by R.~Blumenhagen, B.~Jurke and the authors (arXiv:1003.5217) and suggest a
Computational Tools for Cohomology of Toric Varieties
Applications to the computation of chiral massless matter spectra in string compactifications are discussed, and using the software package cohomCalg, its utility is highlighted on a new target space dual pair of (0,2) heterotic string models.
Cohomology of Line Bundles
In this chapter we compute the dimension of every cohomology group of every line bundle L on a complex torus X = V/∧ (see Theorem 3.5.5). As a direct consequence we get a formula for the
Cohomology on Toric Varieties and Local Cohomology with Monomial Supports
A grading on R which is coarser than the Z^n-grading such that each component of H^i_B(R) is finite dimensional is given and an effective way to compute these components is given.
Cohomology of line bundles: Applications
Massless modes of both heterotic and Type II string compactifications on compact manifolds are determined by vector bundle valued cohomology classes. Various applications of our recent algorithm for
Toric Geometry and Calabi-Yau Compactifications
These notes contain a brief introduction to the construction of toric Calabi--Yau hypersurfaces and complete intersections with a focus on issues relevant for string duality calculations. The last
Cohomology of toric line bundles via simplicial Alexander duality
We give a rigorous mathematical proof for the validity of the toric sheaf cohomology algorithm conjectured in the recent paper by Blumenhagen, Jurke, Rahn, and Roschy (arXiv:1003.5217). We actually
Topological Cohen-Macaulay criteria for monomial ideals
Scattered over the past few years have been several occurrences of simplicial complexes whose topological behavior characterize the Cohen-Macaulay property for quotients of polynomial rings by
Towards the Mirror Symmetry for Calabi-Yau Complete intersections in Gorenstein Toric Fano Varieties
We propose a combinatorical duality for lattice polyhedra which conjecturally gives rise to the pairs of mirror symmetric families of Calabi-Yau complete intersections in toric Fano varieties with
