Symmetry fractionalization and twist defects

open access: yesNew Journal of Physics, 2016
Topological order in two-dimensions can be described in terms of deconfined quasiparticle excitations—anyons—and their braiding statistics. However, it has recently been realized that this data does not completely describe the situation in the presence ...

Cohomology and the subgroup structure of a finite soluble group [PDF]

open access: yes
The main topic of this thesis is the discovery and study of a cohomological property of the subgroups called F-normalizers in finite soluble groups; namely, the property that with certain coefficient modules the restriction map in cohomology from a ...

Algebraic cycles and local anomalies in F-theory

open access: yesJournal of High Energy Physics, 2017
We introduce a set of identities in the cohomology ring of elliptic fibrations which are equivalent to the cancellation of gauge and mixed gauge-gravitational anomalies in F-theory compactifications to four and six dimensions.

Local cohomology in classical rings [PDF]

open access: yes, 1992
The aim of this paper is to stablish the close connection between prime ideals and torsion theories in anon necessarily commutative noetherian ring. We introduce a new definition of support of a module and characterize some kinds of torsion theories in ...

Greenlees-May duality in a nutshell [PDF]

open access: yesSurveys in Mathematics and its Applications, 2019
This expository article delves deep into Greenlees-May Duality which is widely thought of as a far-reaching generalization of Grothendieck's Local Duality.

The Poincaré-Shannon Machine: Statistical Physics and Machine Learning Aspects of Information Cohomology

open access: yesEntropy, 2019
Previous works established that entropy is characterized uniquely as the first cohomology class in a topos and described some of its applications to the unsupervised classification of gene expression modules or cell types.

Local control of group cohomology

open access: yes, 1995
An isomorphism of group cohomology and equivariant cohomology yields a variation of a theorem of P. Webb, describing the p-component of the cohomology with trivial integer coefficients of certain finite groups as an alternating sum of cohomologies of ...

Local (Co)homology and Čech (Co)complexes with Respect to a Pair of Ideals

open access: yesMathematics
Let I and J be two ideals of a commutative ring R. We introduce the concepts of the Cˇech complex and Cˇech cocomplex with respect to (I,J) and investigate their homological properties.

LOCAL SYSTEMS ON COMPLEMENTS OF ARRANGEMENTS OF SMOOTH, COMPLEX ALGEBRAIC HYPERSURFACES

open access: yesForum of Mathematics, Sigma, 2018
We consider smooth, complex quasiprojective varieties $U$ that admit a compactification with a boundary, which is an arrangement of smooth algebraic hypersurfaces. If the hypersurfaces intersect locally like hyperplanes,
