Relative critical loci and quiver moduli
Tristan Bozec, Damien Calaque, Sarah Scherotzke
In this paper we identify the cotangent to the derived stack of representations of a quiver with the derived moduli stack of modules over the Ginzburg dg-algebra associated wit…
An arbitrary-order method for magnetostatics on polyhedral meshes based on a discrete de Rham sequence
Daniele A. Di Pietro, Jérôme Droniou
In this work, we develop a discretisation method for the mixed formulation of the magnetostatic problem supporting arbitrary orders and polyhedral meshes. The method is based on a…
The localization spectral sequence in the motivic setting
Clément Dupont, Daniel Juteau
We construct and study a motivic lift of a spectral sequence associated to a stratified scheme, recently discovered by Petersen in the context of mixed Hodge theory and -adic…
The fate of the axial anomaly in a finite field theory
Pierre Grangé, Jean-François Mathiot, Ernst Werner
The conservation of the vector current and the axial anomaly responsible for the decay amplitude are obtained in leading order within the Taylor-Lagrange formulation o…
Implicit differentiation of Lasso-type models for hyperparameter optimization
Quentin Bertrand, Quentin Klopfenstein, Mathieu Blondel +3
Setting regularization parameters for Lasso-type estimators is notoriously difficult, though crucial in practice. The most popular hyperparameter optimization approach is grid-sear…
