Obstructing Anosov flows on cusped 3‐manifolds

Bulletin of the London Mathematical Society, Volume 57, Issue 5, Page 1584-1592, May 2025.
Abstract Using results relating taut foliations, Heegaard–Floer homology and pseudo‐Anosov flows, we find cusped hyperbolic 3‐manifolds which are not the non‐singular part of a pseudo‐Anosov flow. In particular, we find the first examples of cusped hyperbolic 3‐manifolds not admitting veering triangulations, confirming a conjecture of S. Schleimer.

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Dirac-mode analysis for quark number density and its application for deconfinement transition

EPJ Web of Conferences, 2018
The quark number density at finite imaginary chemical potential is investigated in the lattice QCD using the Dirac-mode expansion. We find the analytical formula of the quark number density in terms of the Polyakov loop in the large quark mass regime. On

Holonomy pseudogroups as obstructions to equivalence of manifolds over the algebra of dual numbers

Учёные записки Казанского университета: Серия Физико-математические науки, 2019
A smooth manifold over the algebra of dual numbers D (a D-smooth manifold) carries the canonical foliation whose leaves are affine manifolds. Extension of charts on a D-smooth manifold along leaf paths allows ones to associate with an immersed ...

Generalized Euler index, holonomy saddles, and wall-crossing

Journal of High Energy Physics, 2020
We formulate Witten index problems for theories with two supercharges in a Majorana doublet, as in d = 3 N $$ \mathcal{N} $$ = 1 theories and dimensional reduction thereof.

Holonomies of intersecting branes [PDF]

Fortschritte der Physik, 2005
AbstractWe discuss the geometry of string and M‐theory gauge fields in Deligne cohomology. In particular, we show how requiring string structure (or loop space SpinC structure) on the five‐brane leads to topological conditions on the flux in the relative Deligne cohomology of the bulk‐brain pair.

Cosmological perturbations in a class of fully covariant modified theories: application to models with the same background as standard LQC

European Physical Journal C: Particles and Fields, 2018
Bouncing cosmologies are obtained by adding to the Einstein–Hilbert action a term of the form $$\sqrt{-\,g}f(\chi )$$ -gf(χ) , with $$\chi $$ χ a scalar depending on the Hubble parameter only, not on its derivatives, and which is here shown to arise from

A Mathematical Bridge between Discretized Gauge Theories in Quantum Physics and Approximate Reasoning in Pairwise Comparisons

Advances in Mathematical Physics, 2018
We describe a mathematical link between aspects of information theory, called pairwise comparisons, and discretized gauge theories. The link is made by the notion of holonomy along the edges of a simplex.

Holonomy Groupoids of Singular Foliations

Journal of Differential Geometry, 2001
The author presents a new construction of Lie groupoids which is particularly well adapted to the generalization of holonomy groupoids of singular foliations. Given a family of local Lie groupoids on open subsets of a manifold satisfying certain conditions, she constructs a Lie groupoid that contains the whole family.

$G_2$-manifolds from 4d N=1 theories, part I: Domain walls

SciPost Physics
We propose new $G_2$-holonomy manifolds, which geometrize the Gaiotto-Kim 4d $\mathcal{N}=1$ duality domain walls of 5d $\mathcal{N}=1$ theories. These domain walls interpolate between different extended Coulomb branch phases of a given 5d superconformal
