Bubble bag end: a bubbly resolution of curvature singularity

Journal of High Energy Physics, 2021
We construct a family of smooth charged bubbling solitons in M $$ \mathbbm{M} $$ 4×T2, four-dimensional Minkowski with a two-torus. The solitons are characterized by a degeneration pattern of the torus along a line in M $$ \mathbbm{M} $$ 4 defining a ...

Ergodicity of Maps on the Two-Dimensional Torus

International Journal of Systems Science and Applied Mathematics
This paper considers the ergodicity of maps on the two-dimensional torus, focusing on transformations where invariant real-valued functions are constant. The study considers both additive and multiplicative transformations, providing a detailed analysis of the conditions required for a map to be classified as ergodic.

Meromorphic mappings of torus onto the Riemann sphere

Karpatsʹkì Matematičnì Publìkacìï, 2012
The meromorphic mappings of the two dimensional torus onto the Riemann sphere are studied. Their connections with loxodromic meromorphic functions in the punctured plane are considered.

Monodromy methods for torus conformal blocks and entanglement entropy at large central charge

Journal of High Energy Physics, 2021
We compute the entanglement entropy in a two dimensional conformal field theory at finite size and finite temperature in the large central charge limit via the replica trick. We first generalize the known monodromy method for the calculation of conformal

Modeling error of \(\alpha\)-models of turbulence on a two-dimensional torus

, 2021
The article focuses on different turbulence models in a two-dimensional periodic domain: the Leray-\(\alpha\) model, the simplified Bardina model, and the modified Leray-\(\alpha\) model, which are obtained from the Navier--Stokes equations by certain regularizations of the nonlinear term.

Complete Invariants for Hamiltonian Torus Actions with Two Dimensional Quotients [PDF]

Journal of Symplectic Geometry, 2004
We study torus actions on symplectic manifolds with proper moment maps in the case that each reduced space is two-dimensional. We provide a complete set of invariants for such spaces. Our proof uses sheaves of groupoids of Hamiltonian spaces.
