Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Arithmetic rigidity and units in group rings
, 2001 For any finite group G the group U(Z[G]) of units in the integral group ring Z[G]is an arithmetic group in a reductive algebraic group, namely the Zariski closure of SL1 (Q[G]).

Weak, Strong and Mixed Extensions of Relations to Spaces of Ultrafilters
Mathematical Logic Quarterly, Volume 72, Issue 3, August 2026.ABSTRACT The use of nonstandard methods to characterize properties of weak, strong and mixed extensions of congruences to ultrafilters has been the main topic of several recent papers, focused mostly on congruences and divisions. We show that similar methods can be used to extend these characterizations to arbitrary relations and their interplay.

Studies on the number theory of orders
, 1982 Bibliography: pages 78-81.In the nineteenth century no distinction was drawn between maximal and nonmaximal orders in a numberfield. Most of the work on orders in this period was done by Dedekind and Kronecker.

Belyi Function whose Grothendieck Dessin is a Flower Tree with Two Ramification Indices
, 2005 In this paper we present an explicit construction of Belyi functions whose dessins are flower trees (i.e., graphs of diameter 4) with two ramification indices.

Journal of Child Psychology and Psychiatry, Volume 67, Issue 7, Page 1127-1146, July 2026.Background Conflict and crises have long‐lasting and dramatic consequences on the mental health of children. We aimed to investigate the effectiveness of a psychosocial intervention on child mental health in Afghanistan. Methods A two‐arm cluster‐randomized controlled trial was conducted in 83 rural primary schools within three provinces of Afghanistan.

On p-Adic Estimates of Weights in Abelian Codes over Galois Rings [PDF]
, 2005 Let p be a prime. We prove various analogues and generalizations of McEliece's theorem on the p-divisibility of weights of words in cyclic codes over a finite field of characteristic p. Here we consider Abelian codes over various Galois rings.
