Exact splitting methods for kinetic and Schr{ö}dinger equations
Joackim Bernier, Nicolas Crouseilles, Yingzhe Li
In [8], some exact splittings are proposed for inhomogeneous quadratic differential equations including, for example, transport equations, kinetic equations, and Schr{ö}dinger type…
Famille admise associée à une valuation de K(X)
Michel Vaquié
Let K be a field with a valuation and let L = K(x) be a transcendental extension of K, then any valuation of L which extends is determined by its restriction to the pol…
Conditional measures for Pfaffian point processes: conditioning on a bounded domain
Alexander I. Bufetov, Fabio Deelan Cunden, Yanqi Qiu
For a Pfaffian point process we show that its Palm measures, its normalised compositions with multiplicative functionals, and its conditional measures with respect to fixing the co…
High order numerical schemes for transport equations on bounded domains
Benjamin Boutin, Thi Hoai Thuong Nguyen, Abraham Sylla +2
This article is an account of the NABUCO project achieved during the summer camp CEMRACS 2019 devoted to geophysical fluids and gravity flows. The goal is to construct finite diffe…
Exact splitting methods for semigroups generated by inhomogeneous quadratic differential operators
Joackim Bernier
We introduce some general tools to design exact splitting methods to compute numerically semigroups generated by inhomogeneous quadratic differential operators. More precisely, we…
Unramified Heisenberg group extensions of number fields
Frauke Bleher, Ted Chinburg, Jean Gillibert
We construct étale generalized Heisenberg group covers of hyperelliptic curves over number fields. We use these to produce infinite families of quadratic extensions of cyclotomic f…
