Equations for polar Grassmannians [PDF]
Linear and Multilinear Algebra, 2016 Given an $N$-dimensional vector space $V$ over a field $\mathbb{F}$ and a trace-valued $( ,\varepsilon)$-sesquilinear form $f:V\times V\rightarrow \mathbb{F}$, with $\varepsilon = \pm 1$ and $ ^2 = \mathrm{id}_{\mathbb{F}}$, let ${\cal S}$ be the polar space of totally $f$-isotropic subspaces of $V$ and let $n$ be the rank of ${\cal S}$. Assuming $n \

Remarks on some infinitesimal symmetries of Khovanov–Rozansky homologies in finite characteristic
Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3597-3613, November 2025.Abstract We give a new proof of a theorem due to Shumakovitch and Wang on base point independence of Khovanov–Rozansky homology in characteristic p$p$. Some further symmetries of gl(p)$\mathfrak {gl}(p)$‐homology in characteristic p$p$ are also discussed.

Quasi‐projective varieties are Grassmannians for fully exact subcategories of quiver representations
Bulletin of the London Mathematical Society, Volume 57, Issue 9, Page 2748-2756, September 2025.Abstract Reineke and independent other authors proved that every projective variety arises as a quiver Grassmannian. We prove the claim in the title by restricting Reineke's isomorphism to Grassmannians for a fully exact subcategory.

Symplectic Grassmannian description of the Coulomb branch three and four point amplitudes
Journal of High Energy PhysicsWe present a formulation of the three- and four-point amplitudes on the Coulomb branch of N $$ \mathcal{N} $$ = 4 SYM as integrals over the symplectic Grassmannian.

Rank-metric codes as ideals for subspace codes and their weight properties
AKCE International Journal of Graphs and Combinatorics, 2019 Let q=pr, p a prime, r a positive integer, and Fqthe Galois field with cardinality q and characteristic p. In this paper, we study some weight properties of rank-metric codes and subspace codes. The rank weight is not egalitarian nor homogeneous, and the

Grassmannian and elliptic operators
, 1997 The conjecture about relation between infinite-dimensional Grassmannian and string theory is based on the fact that moduli spaces of algebraic curves are embedded into Grassmannian via Krichever construction.

Analysis of density matrix embedding theory around the non‐interacting limit
Communications on Pure and Applied Mathematics, Volume 78, Issue 8, Page 1359-1410, August 2025.Abstract This article provides the first mathematical analysis of the Density Matrix Embedding Theory (DMET) method. We prove that, under certain assumptions, (i) the exact ground‐state density matrix is a fixed‐point of the DMET map for non‐interacting systems, (ii) there exists a unique physical solution in the weakly‐interacting regime, and (iii ...

Discrete Integrable Principal Chiral Field Model and Its Involutive Reduction
Studies in Applied Mathematics, Volume 155, Issue 2, August 2025.ABSTRACT We discuss an integrable discretization of the principal chiral field models equations and its involutive reduction. We present a Darboux transformation and general construction of soliton solutions for these discrete equations.
