Tannakian duality and Gauss-Manin connections for a family of curves
Phùng Hô Hai, Võ Quôc Bao, Trân Phan Quôc Bao
Let be a smooth family of smooth projective varieties, where is a smooth affine curve over a field of characteristic We relate the differential fundamental group…
Two small remarks on Nori fundamental group scheme
Hélène Esnault, Phùng Hô Hai
For a complete, reduced, geometrically connected scheme over a perfect field of characteristic , we analyze the decomposition of Nori's fundamental group scheme into its l…
N-homogeneous superalgebras
Phung Ho Hai, Benoit Kriegk, Martin Lorenz
We develop the theory of N-homogeneous algebras in a super setting, with particular emphasis on the Koszul property. To any Hecke operator on a vector superspace, we associate cert…
The fundamental groupoid scheme and applications
Hélène Esnault, Phùng Hô Hai
We define a linear structure on Grothendieck's arithmetic fundamental group of a scheme defined over a field of characteristic 0. It allows us to link the exist…
A construction of a quotient tensor category
Phung Ho Hai
For a rigid tensor abelian category over a field we introduce a notion of a normal quotient . In case is a Tannaka category, our notion is equivalent to Milne…
Koszul algebras and the quantum MacMahon Master Theorem
Phung Ho Hai, Martin Lorenz
We give a new proof of the quantum version of MacMahon's Master Theorem due to Garoufalidis, Le and Zeilberger (one-parameter case) and to Konvalinka and Pak (multiparameter case)…
