A variational principle for computing slow invariant manifolds in dissipative dynamical systems [PDF]
, 2009 A key issue in dimension reduction of dissipative dynamical systems with spectral gaps is the identification of slow invariant manifolds. We present theoretical and numerical results for a variational approach to the problem of computing such manifolds ...

Moduli space holography and the finiteness of flux vacua
Journal of High Energy Physics, 2021 A holographic perspective to study and characterize field spaces that arise in string compactifications is suggested. A concrete correspondence is developed by studying two-dimensional moduli spaces in supersymmetric string compactifications.

Infinitely many M2-instanton corrections to M-theory on G 2-manifolds
Journal of High Energy Physics, 2018 We consider the non-perturbative superpotential for a class of four-dimensional N=1 $$ \mathcal{N}=1 $$ vacua obtained from M-theory on seven-manifolds with holonomy G 2. The class of G 2-holonomy manifolds we consider are so-called twisted connected sum

Categorical Smoothness of 4-Manifolds from Quantum Symmetries and the Information Loss Paradox
Entropy, 2022 In this paper, we focus on some aspects of the relation of spacetime and quantum mechanics and the study counterparts (in Set) of the categorical local symmetries of smooth 4-manifolds.

Nonnegative curvature, low cohomogeneity and complex cohomology [PDF]
, 2016 We construct several infinite families of nonnegatively curved manifolds of low cohomogeneity and small dimension which can be distinguished by their cohomology rings. In particular, we exhibit an infinite family of eight-dimensional cohomogeneity one

(2, 2) geometry from gauge theory
Journal of High Energy Physics, 2018 Using gauge theory, we describe how to construct generalized Kähler geometries with (2, 2) two-dimensional supersymmetry, which are analogues of familiar examples like projective spaces and Calabi-Yau manifolds. For special cases, T-dual descriptions can

Quasinormal forms for systems of two equations with large delay [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамикаA system of two equations with delay is considered. The purpose of this work is to study the local dynamics of this system under the assumption that the delay parameter is sufficiently large.

FEBS Open Bio, EarlyView.Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Partial Differential Equations in Applied MathematicsWe study the well-known generalised version of the nonlinear Cahn–Hilliard evolution equation, supplemented with periodic boundary conditions. We study local bifurcations in the vicinity of spatially homogeneous equilibrium states.

Numerical Approximation of LYAPUNOV-Exponents for Quasiperiodic Motions
MATEC Web of Conferences, 2018 This paper proposes an approach to approximate the LYAPUNOV -spectrum of quasiperiodic flows on isolated invariant manifolds numerically. Once the invariant manifold has been determined, integrations over the infinite, one dimensional time interval – as ...
