On the fundamental group schemes of certain quotient varieties
Indranil Biswas, Phùng Hô Hai, João Pedro dos Santos
In \cite{armstrong}, M. Armstrong proved a beautiful result describing fundamental groups of quotient spaces. In this paper we prove an analogue of Armstrong's theorem in the setti…
Jacobi-Trudi type formula for character of irreducible representations of
Nguyen Luong Thai Binh, Nguyen Thi Phuong Dung, Phung Ho Hai
We prove a determinantal type formula to compute the irreducible characters of the general Lie superalgebra in terms of the characters of the symmetric powers…
On the structure of affine flat group schemes over discrete valuation rings, II
Phùng Hô Hai, João Pedro dos Santos
In the 1st part of this work [DHdS18], we studied affine group schemes over a discrete valuation ring (DVR) by means of Neron blowups. We also showed how to apply these findings to…
