Weak-type interpolation for noncommutative maximal operators
Sjoerd Dirksen
We prove a Boyd-type interpolation result for noncommutative maximal operators of restricted weak type. Our result positively answers an open question posed recently by Bekjan, Che…
Almost conical deformations of thin sheets with rotational symmetry
Stefan Müller, Heiner Olbermann
It has been found in numerical experiments that when one removes a sector from an elastic sheet and glues the edges of the sector back together, the resulting configuration is radi…
Constrained energy minimization and orbital stability for the NLS equation on a star graph
R. Adami, C. Cacciapuoti, D. Finco +1
We consider a nonlinear Schrödinger equation with focusing nonlinearity of power type on a star graph , written as , wh…
Norms as products of linear polynomials
Damaris Schindler, Alexei Skorobogatov
Let F be a number field, and let F\subset K be a field extension of degree n. Suppose that we are given 2r sufficiently general linear polynomials in r variables over F. Let X be t…
Nonexistence of extremizers for certain convex curves
Diogo Oliveira e Silva
We establish the nonexistence of extremizers for a local Fourier restriction inequality on a certain class of planar convex curves whose curvature satisfies a natural assumption. W…
Itô isomorphisms for -valued Poisson stochastic integrals
Sjoerd Dirksen
Motivated by the study of existence, uniqueness and regularity of solutions to stochastic partial differential equations driven by jump noise, we prove Itô isomorphisms for -v…
