Godement resolutions and sheaf homotopy theory
(Springer, 2015-09)The Godement cosimplicial resolution is available for a wide range of categories of sheaves. In this paper we investigate ...

Grothendieck bialgebras, Partition lattices, and symmetric functions in noncommutative variables
(American Mathematical Society, 2006)We show that the Grothendieck bialgebra of the semi-tower of partition lattice algebras is isomorphic to the graded dual ...

Gröbner δ-bases and Gröbner bases for differential operators
(Polish Academy of Sciences, Institute of Mathematics, 2002)This paper deals with the notion of Gr¨obner δ-base for some rings of linear differential operators by adapting the works ...

Hasse-Schmidt derivations and coefficient fields in positive characteristics
(Elsevier, 2003-07-01)We show how to express any Hasse-Schmidt derivation of an algebra in terms of a finite number of them under natural ...

Hasse-Schmidt derivations, divided powers and differential smoothness
(Association des Annales de l'Institut Fourier, 2009)Let k be a commutative ring, A a commutative k-algebra and D the filtered ring of k-linear differential operators of A. ...

Higher derivations of modules and the Hasse-Schmidt module
(Cornell University, 2020-07-28)In this paper we revisit Ribenboim's notion of higher derivations of modules and relate it to the recent work of De Fernex ...

Hodge ideals of free divisors
(Springer, 2022-04-18)We consider the Hodge filtration on the sheaf of meromorphic functions along free divisors for which the logarithmic ...

Homotopy theory of bicomplexes
(Elsevier, 2019-05)We define two model structures on the category of bicomplexes concentrated in the right half plane. The first model ...

Homotopy theory of nonsymmetric operads
(Mathematical Sciences Publishers, 2011)We endow categories of nonsymmetric operads with natural model structures. We work with no restriction on our operads and ...
