Classification of single-bubble blow-up solutions for Calogero--Moser derivative nonlinear Schr\"odinger equation
arXiv:2601.07410v1 Announce Type: new Abstract: We study the Calogero--Moser derivative nonlinear Schr\"odinger equation (CM-DNLS), a mass-critical and completely integrable dispersive model. Recent works established finite-time blow-up constructions and soliton resolution, describing the asymptotic behaviors of blow-u...

Rigidity of the escaping set of polynomial automorphisms of $\mathbb{C}^2$
arXiv:2601.07681v1 Announce Type: new Abstract: Let $H$ be a polynomial automorphism of $\mathbb{C}^2$ of positive entropy and degree $d \ge 2$. We prove that the escaping set $U^+$ (or equivalently, the non-escaping set $K^+$), of $H$ is rigid under the action of holomorphic automorphisms of $\mathbb{C}^2$. Specifical...

Three Combinatorial Algorithms for the Cave Polynomial of a Polymatroid
arXiv:2601.07697v1 Announce Type: new Abstract: The cave polynomial of a polymatroid was recently introduced and used to study the syzygies of polymatroidal ideals. We study the combinatorial relationships between three formulas for the cave polynomial. As an application, we interpret the Snapper polynomial in terms of...

Asymptotic-M\"obius maps
arXiv:2601.07702v1 Announce Type: new Abstract: We introduce asymptotic-M\"obius (AM) maps, a large-scale analogue of quasi-M\"obius maps tailored to geometric group theory. AM-maps capture coarse cross-ratio behavior for configurations of points that lie far apart, providing a notion of "conformality at infinity" that...

arXiv:2601.06638v1 Announce Type: cross Abstract: Population balance equations (PBEs) for pure fragmentation describe how particle size distributions (PSDs) evolve under breakage and fragment redistribution. We map a self-similar fragmentation class to: a conservative pure-jump master equation in log-size space; an exa...
