Bridges and random truncations of random matrices
Vincent Beffara, Catherine Donati-Martin, Alain Rouault
We continue to study the squared Frobenius norm of a submatrix of a random unitary matrix. When the choice of the submatrix is deterministic and its size is $[ns] \tim…
LDB division algebras
Clément de Seguins Pazzis
An LDB division algebra is a triple in which and are regular bilinear laws on the finite-dimensional non-zero vector space such that $x \s…
Compact homogeneous lcK manifolds are Vaisman
Paul Gauduchon, Andrei Moroianu, Liviu Ornea
We prove that any compact homogeneous locally conformally Kähler manifold has parallel Lee form.
Large deviations and Gallavotti-Cohen principle for dissipative PDE's with rough noise
Vojkan Jaksic, Vahagn Nersesyan, Claude-Alain Pillet +1
We study a class of dissipative PDE's perturbed by an unbounded kick force. Under some natural assumptions, the restrictions of solutions to integer times form a homogeneous Markov…
Projected Gromov-Witten varieties in cominuscule spaces
Anders S. Buch, Pierre-Emmanuel Chaput, Leonardo C. Mihalcea +1
A projected Gromov-Witten variety is the union of all rational curves of fixed degree that meet two opposite Schubert varieties in a homogeneous space X = G/P. When X is cominuscul…
Pillars and globules at the edges of H ii regions, Confronting Herschel observations and numerical simulations
P. Tremblin, V. Minier, N. Schneider +24
Pillars and globules are present in many high-mass star-forming regions, such as the Eagle nebula (M16) and the Rosette molecular cloud, and understanding their origin will help ch…
