A construction of semi-infinite de Rham cohomology [PDF]

The purpose of this thesis is to describe a construction of semi-infinite de Rham cohomology for infinite dimensional manifolds equipped with the extra structure of a polarisation.

The spectrum of the bosonic ambitwistor string revisited

Journal of High Energy Physics
We revisit the calculation of the spectrum of the bosonic ambitwistor string, understood as the BRST cohomology or, equivalently, as the semi-infinite cohomology of the BMS3 Lie algebra relative to the centre with values in a particular module.

The homotopy type of toric arrangements [PDF]

A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we build a CW-complex S homotopy equivalent to the arrangement complement ℜ x, with a combinatorial ...

The ?2-cohomology of hyperplane complements

, 2007
We compute the l^2-Betti numbers of the complement of any finite collection of affine hyperplanes in complex n-space. At most one of the l^2-Betti numbers is non-zero.

Cohomology theories [PDF]

, 2011
En este trabajo se construirán la cohomología singular, la cohomología de Cech relativa a un buen cubrimiento y la cohomología de De Rham en manifolds suaves y se mostrará la equivalencia entre algunas de estas./Abstract: In this paper we will construct ...

Abelian Extensions of Modified λ-Differential Left-Symmetric Algebras and Crossed Modules

Axioms
In this paper, we define a cohomology theory of a modified λ-differential left-symmetric algebra. Moreover, we introduce the notion of modified λ-differential left-symmetric 2-algebras, which is the categorization of a modified λ-differential left ...

Quantum cohomology from mixed Higgs-Coulomb phases

Journal of High Energy Physics
We generalize Coulomb-branch-based gauged linear sigma model (GLSM)–computations of quantum cohomology rings of Fano spaces. Typically such computations have focused on GLSMs without superpotential, for which the low energy limit of the GLSM is a pure ...

Some problems in algebraic topology: systems of higher order cohomology operations in the p-torsion-free category [PDF]

, 1979
In this thesis, we establish a pair of systems of higher order cohomology operations that act on the Ζp-ordinary cohomology of spaces that are free of p-torsion.
