Mathematics, 2023 We obtain some generalized Minkowski type integral formulas for compact Riemannian (resp., spacelike) hypersurfaces in Riemannian (resp., Lorentzian) manifolds in the presence of an arbitrary vector field that we assume to be timelike in the case where ...

Non-toric cones and Chern-Simons quivers
Journal of High Energy Physics, 2017 We obtain an integral formula for the volume of non-toric tri-Sasaki Einstein manifolds arising from nonabelian hyperkähler quotients. The derivation is based on equivariant localization and generalizes existing formulas for Abelian quotients, which lead

Feynman Path Integral Variation On Lorentz Manifolds
, 2021 This paper is analyzing the 8-theory framework and the Feynman path integral formulation and seek to reach a synthesis which will lead to an effective technique of finding transition amplitudes on Lorentz Manifolds.

On the non-autonomous Hopf bifurcation problem: systems with rapidly varying coefficients.
Electronic Journal of Qualitative Theory of Differential Equations, 2019 We consider a $2$-dimensional ordinary differential equation (ODE) depending on a parameter $\epsilon$. If the ODE is autonomous the supercritical Andronov–Hopf bifurcation theory gives sufficient conditions for the genesis of a repeller–attractor pair ...

Integration of Differential Graded Manifolds [PDF]
International Mathematics Research Notices, 2019 Abstract We consider the problem of integration of $L_\infty $-algebroids (differential non-negatively graded manifolds) to $L_\infty $-groupoids. We first construct a “big” Kan simplicial manifold (Fréchet or Banach) whose points are solutions of a (generalized) Maurer–Cartan equation.

Odd manifolds of small integral simplicial volume
, 2018 Integral simplicial volume is a homotopy invariant of oriented closed connected manifolds, defined as the minimal weighted number of singular simplices needed to represent the fundamental class with integral coefficients.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

3 definitions of BF theory on homology 3-spheres
Journal of High Energy Physics, 2023 3-dimensional BF theory with gauge group G (= Chern-Simons theory with non-compact gauge group TG) is a deceptively simple yet subtle topological gauge theory.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
