Equivariant D-modules combine the algebraic theory of differential operators with group actions on algebraic varieties, providing a framework to study systems of linear partial differential equations ...

Algebraic structures such as semirings and modules have long been a fertile ground for both theoretical exploration and practical application. Semirings, generalisations of rings that typically lack ...

Masaki Kashiwara, project professor at Kyoto University’s Research Institute for Mathematical Sciences, has been awarded the ...

The Virasoro vertex algebra arises as the symmetry algebra of a two-dimensional conformal field theory. The Virasoro irreducible modules are well-known, and they play a prominent role in rational ...
