Local rigidity, symplectic homeomorphisms, and coisotropic submanifolds [PDF]

open access: yesBulletin of the London Mathematical Society, 2022
We introduce the notion of a point on a locally closed subset of a symplectic manifold being "locally rigid" with respect to that subset, prove that this notion is invariant under symplectic homeomorphisms, and show that coisotropic submanifolds are distinguished among all smooth submanifolds by the property that all of their points are locally rigid ...

Minimal homogeneous submanifolds in euclidean spaces [PDF]

open access: yes, 2002
We prove that minimal (extrinsically) homogeneous submanifolds of the Euclidean space are totally geodesic. As an application, we obtain that a complex (intrisecally) homogeneous submanifold of a complex Euclidean space must be totally ...

Submanifolds with curvature normals of constant length and the Gauss map [PDF]

open access: yes, 2004
We show that a submanifold with curvature normal of constant length has constant principal curvatures under suitable global hypothesis.

PETIMOT: a novel framework for inferring protein motions from sparse data using SE(3)-equivariant graph neural networks. [PDF]

open access: yesActa Crystallogr D Struct Biol
We present a new formulation for protein flexibility and learn protein motions from sparse experimental data.Proteins move and deform to ensure their biological functions. Despite significant progress in protein structure prediction, approximating conformational ensembles under physiological conditions remains a fundamental open problem.

Reducibility of complex submanifolds of the complex euclidean spaces [PDF]

open access: yes, 2000
Let M be a simply connected complex submanifold of CN. We prove that M is irreducible, up a totally geodesic factor,if and only if the normal holonomy group acts irreducibly.

Jordan-Wigner dualities for translation-invariant Hamiltonians in any dimension: Emergent fermions in fracton topological order

open access: yesPhysical Review Research, 2020
Inspired by recent developments generalizing Jordan-Wigner dualities to higher dimensions [Ann. Phys. 393, 234 (2018)APNYA60003-491610.1016/j.aop.2018.03.024], we develop a framework of such dualities using an algebraic formalism for translation ...

The geometry of the Hermitian matrix space and the Schrieffer–Wolff transformation [PDF]

open access: yesQuantum
In quantum mechanics, the Schrieffer–Wolff (SW) transformation (also called quasi-degenerate perturbation theory) is known as an approximative method to reduce the dimension of the Hamiltonian.
