Perturbative-Iterative Computation of Inertial Manifolds of Systems of Delay-Differential Equations with Small Delays

Algorithms, 2020
Delay-differential equations belong to the class of infinite-dimensional dynamical systems. However, it is often observed that the solutions are rapidly attracted to smooth manifolds embedded in the finite-dimensional state space, called inertial ...

Type IIB flux compactifications with h 1,1 = 0

Journal of High Energy Physics, 2022
We revisit flux compactifications of type IIB string theory on ‘spaces’ dual to rigid Calabi-Yau manifolds. This rather unexplored part of the string landscapes harbors many interesting four-dimensional solutions, namely supersymmetric N $$ \mathcal{N} $$

Higher-derivative supergravity, wrapped M5-branes, and theories of class ℛ $$ \mathrm{\mathcal{R}} $$

Journal of High Energy Physics, 2021
We study the interplay between four-derivative 4d gauged supergravity, holography, wrapped M5-branes, and theories of class ℛ $$ \mathrm{\mathcal{R}} $$ .

Strong ellipticity and spectral properties of chiral bag boundary conditions [PDF]

, 2003
We prove strong ellipticity of chiral bag boundary conditions on even dimensional manifolds. From a knowledge of the heat kernel in an infinite cylinder, some basic properties of the zeta function are analyzed on cylindrical product manifolds of ...

Normalized boundary value problems in the model of optoelectronic oscillator delayed [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика, 2020
Purpose of this work is reduction of differential-difference-model of optic-electronic oscillator to more simple normalized boundary value problems. We study the dynamics of an optoelectronic oscillator with delayed feedback in the vicinity of the zero ...

5-dimensional space-periodic solutions of the static vacuum Einstein equations

Journal of High Energy Physics, 2020
An affirmative answer is given to a conjecture of Myers concerning the existence of 5-dimensional regular static vacuum solutions that balance an infinite number of black holes, which have Kasner asymptotics. A variety of examples are constructed, having

Dense Sigma-Compact Subsets of Infinite-Dimensional Manifolds.

, 1971
In this paper four classes of separable metric infinite-dimensional manifolds are studied; those which are locally the countable infinite product of lines, those which are locally open subsets of the Hilbert cube, and those which are locally one of two ...

Local dynamics of laser chain model with optoelectronic delayed unidirectional coupling [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика, 2022
Purpose. The local dynamics of the laser chain model with optoelectronic delayed unidirectional coupling is investigated. A system of equations is considered that describes the dynamics of a closed chain of a large number of lasers with optoelectronic ...

Embedding Feynman integral (Calabi-Yau) geometries in weighted projective space

Journal of High Energy Physics, 2020
It has recently been demonstrated that Feynman integrals relevant to a wide range of perturbative quantum field theories involve periods of Calabi-Yau manifolds of arbitrarily large dimension.
