Consider the sub-Riemannian Heisenberg group H. In this paper, we answer the following question: given a compact set K subset of R and a continuous ma......

We prove the local well-posedness for the generalized Korteweg-de Vries equation in Hs.R/, s > 1=2, under general assumptions on the nonlinearity f......

In this paper, we establish curvature estimates for p-convex hypersur-faces in Rn+1 of prescribed curvature with p ⠕ n=2. The existence of a star-shap......

It is a classical theorem of Sarason that an analytic function of bounded mean oscillation (BMOA) is of vanishing mean oscillation if and only if its ......

We prove polynomial upper bounds on the growth of solutions to the 2d cubic nonlinear Schrodinger equation where the Laplacian is confined by the harm......

We show that there exists a bounded subset of R such that no system of exponentials can be a Riesz basis for the corresponding Hilbert space. An addit......

In this paper, we consider the p-Laplacian with potential terms on a connected, noncompact, complete weighted Riemannian manifold whose Ricci cur-vatu......

We extend the Hairer reconstruction theorem for distributions due to Caravenna and Zambotti [EMS Surv. Math. Sci. 7 (2020), 207-251] to general functi......

We show an analogue of Cauchy's surface area formula for the Heisen-berg groups Iffn for n > 1, which states that the p-area of any compact hypersu......

Given any non-compact real simple Lie group Go of inner type and even dimension, we prove the existence of an invariant complex structure J and a Her-......

We prove that the solvability of the regularity problem in Lq(@S2) is sta-ble under Carleson perturbations. If the perturbation is small, then the sol......

Jointly controlled paths as used in Gerasimovics and Hairer (2019), are a class of two-parameter paths Y controlled by a p-rough path X for 2 <= p ......

Let p be a prime number and let & xi; be an irrational p-adic number. Its multiplicative irrationality exponent & mu;X(& xi;) is the supre......

We study the solvability of the regularity problem for degenerate elliptic operators in the block case for data in weighted spaces. More precisely, le......
