Generic submanifolds of a locally conformal Kaehler manifold‐II [PDF]

International Journal of Mathematics and Mathematical Sciences, 1991
A submanifold \(M\) of an almost Hermitian manifold \(\overline {M}\) is called a generic submanifold if its maximal complex subspaces form a differential distribution (cf. [\textit{B. Y. Chen}, Monatsh. Math. 91, 257- 274 (1981; Zbl 0451.53041)]).

Marginally trapped submanifolds in Lorentzian space forms and in the Lorentzian product of a space form by the real line [PDF]

, 2015
We give local, explicit representation formulas for n-dimensional spacelike submanifolds which are marginally trapped in the Minkowski space, the de Sitter and anti de Sitter spaces and the Lorentzian products of the sphere and the hyperbolic space by ...

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

Physical 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 ...

Symplectic Microgeometry II: Generating functions [PDF]

, 2011
We adapt the notion of generating functions for lagrangian submanifolds to symplectic microgeometry. We show that a symplectic micromorphism always admits a global generating function.

Fourier integrals operators on lie groupoids [PDF]

, 2016
As announced in [12], we develop a calculus of Fourier integral G-operators on any Lie groupoid G. For that purpose, we study convolability and invertibility of Lagrangian conic submanifolds of the symplectic groupoid T * G.

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

Quantum
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.

Algebraic higher symmetry and categorical symmetry: A holographic and entanglement view of symmetry

Physical Review Research, 2020
A global symmetry (0-symmetry) in an n-dimensional space acts on the whole space. A higher symmetry acts on closed submanifolds (i.e., loops and membranes, etc.), and those transformations form a higher group.

Time and dark matter from the conformal symmetries of Euclidean space [PDF]

, 2014
The quotient of the conformal group of Euclidean 4-space by its Weyl subgroup results in a geometry possessing many of the properties of relativistic phase space, including both a natural symplectic form and non-degenerate Killing metric.

Normal Anti-Invariant Submanifolds of Paraquaternionic Kähler Manifolds [PDF]

Surveys in Mathematics and its Applications, 2006
We introduce normal anti-invariant submanifolds of paraquaternionic Kähler manifolds and study the geometric structures induced on them. We obtain necessary and sufficient conditions for the integrability of the distributions defined on a normal anti ...

Brownian bridges to submanifolds [PDF]

, 2017
We introduce and study Brownian bridges to submanifolds. Our method involves proving a general formula for the integral over a submanifold of the minimal heat kernel on a complete Riemannian manifold.
