Estimates of Christoffel function on multivariate domains [PDF]
, 2019 We consider Christoffel functions defined on some compact multivariate domain with non-empty interior. Christoffel functions have applications in different problems of approximation theory, harmonic analysis, numerical analysis, statistical physics ...

Regeneration of the lizard heart after cryoinjury
Experimental Physiology, Volume 111, Issue 7, Page 3310-3321, 1 July 2026.Abstract Lizards are renowned for their tremendous potential to heal tissues and organs after injury, but little is known about myocardial regeneration in reptiles generally. Here, we study cardiac regeneration in the leopard gecko (Eublepharis macularius) to fill the knowledge gap between traditional models of poikilothermic (zebrafish) and ...

Stabilized Finite Elements for Incompressible, Stationary Navier–Stokes Flows on Manifolds
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT A surface finite element method with residual‐based stabilization for stationary Navier–Stokes flows on curved manifolds is introduced. The mixed formulation in stress‐divergence form leads to a system of equations that has a saddle‐point structure.

Fortschritte der Physik, Volume 74, Issue 6, June 2026.ABSTRACT We present a clear, step‐by‐step method for counting degrees of freedom and identifying constraints in general field theories. This approach, grounded in the works of Einstein, Hilbert, Cartan, Kuranishi, and, more recently, Seiler, is neither Lagrangian nor Hamiltonian in nature. Instead, it applies directly to the field equations. We offer a

Propriétés d'équilibre sur les mots de Christoffel et applications. [PDF]
, 2017 Many researchers have been interested in studying Combinatorics on Words in theoretical andpractical points of view. Many families of words appeared during these years of research some ofthem are infinite and others are finite.

A Numerical Method for Schwarz-Christoffel Conformal Transformation with Application to Potential Flow in Channels with Oblique Sub-channels [PDF]
, 2000 The potential flow in a semi-infinite channel with multiple semi-infinite oblique sub-channels is determined using the Schwarz-Christoffel transformation and complex potential theory. The standard iterative technique, i.e.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract In situ CO2 mineral storage is gaining increasing attention as a carbon capture and storage (CCS) technology to reduce anthropogenic CO2 emissions. So far, in situ CO2 mineral storage projects have been monitored predominantly using fluid‐ and isotope geochemical methods.

Higher-order recurrence relations, Sobolev-type inner products and matrix factorizations [PDF]
, 2022 It is well known that Sobolev-type orthogonal polynomials with respect to measures supported on the real line satisfy higher-order recurrence relations and these can be expressed as a (2N + 1)-banded symmetric semi-infinite matrix.

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons
Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\
