Upper bounds for measures on distal classes
Ilia Nekrasov, Andrew Snowden
In recent work, Harman and Snowden introduced a notion of measure on a Fraïssé class , and showed how such measures lead to interesting tensor categories. Constructin…
Overgroups of exterior powers of an elementary group. Normalizers
Roman Lubkov, Ilia Nekrasov
We establish two characterizations of an algebraic group scheme over . Geometrically, the scheme is a stabilizer of an explicitly…
Arboreal tensor categories
Nate Harman, Ilia Nekrasov, Andrew Snowden
We introduce some new symmetric tensor categories based on the combinatorics of trees: a discrete family , for an integer, and a continuous family $\mathc…
Dual Infinite Wedge is -equivariantly noetherian
Ilia Nekrasov
We prove the (equivariant) noetherian property for a wide class of varieties generalizing the class of Plucker varieties (Theorem 1). It improves previous results of Draisma-Eggerm…
Compactifications of associated with Alexander self-dual complexes: Chow ring, -classes and intersection numbers
Ilia Nekrasov, Gaiane Panina
An Alexander self-dual complex gives rise to a compactification of , called ASD compactification, which is a smooth algebraic variety. ASD compactifications include (but a…
Geometric presentation for the cohomology ring of polygon spaces
Ilia Nekrasov, Gaiane Panina
We describe the cohomology ring of the moduli space of a flexible polygon in geometrically meaningful terms. We propose two presentations, both are computation friendly: there are…
