A note on η-quasi-umbilical hypersurfaces in almost Hermitian manifolds
Дифференциальная геометрия многообразий фигур, 2023 In the present note, we consider the introduced by Lidia Vasil’evna Stepanova notion of an -quasi-umbilical hypersurface in an almost Hermitian manifold.

A generalized 4d Chern-Simons theory
Journal of High Energy Physics, 2023 A generalization of the 4d Chern-Simons theory action introduced by Costello and Yamazaki is presented. We apply general arguments from symplectic geometry concerning the Hamiltonian action of a symmetry group on the space of gauge connections defined on

MathematicsThis paper undertakes a detailed study of η-Ricci–Bourguignon solitons on ϵ-Kenmotsu manifolds, with particular focus on three special types of Ricci tensors: Codazzi-type, cyclic parallel and cyclic η-recurrent tensors that support such solitonic ...

Emergence in string theory and Fermi gases
Journal of High Energy PhysicsThe Emergence Proposal suggests that some Swampland criteria, in particular on large field distances, are a consequence of the emergent nature of dynamics for fields in the infrared.

Methods of generalized Hermitian geometry in the theory of almost-contact manifolds
Journal of Soviet Mathematics, 1988Applying the geometry of generalized almost-Hermitian structures as an apparatus, a close classification of almost-contact metric manifolds is attempted. Since this apparatus stands on the concept of a Q-algebra over a ring with involution, the first chapter presents its algebraic aspect, revealing the antilinearity of the composition operators, the ...

Deformation quantization of contact manifolds
Letters in Mathematical Physics, 2022 We extend Fedosov deformation quantization to general contact manifolds. Unlike the case of symplectic manifolds, not every classical observable on a contact manifold is generally quantized.
