Functional inequalities for Nonlocal Dirichlet Forms With Finite Range Jumps or Large Jumps
Xin Chen, Jian Wang
The paper is a continuation of our paper [12,2], and it studies functional inequalities for non-local Dirichlet forms with finite range jumps or large jumps. Let and $μ…
The research program of Stochastic Deformation (with a view toward Geometric Mechanics)
Jean-Claude Zambrini
We give an overview of a program of Stochastic Deformation of Classical Mechanics and the Calculus of Variations, strongly inspired by the quantization method.
A deformation of the method of characteristics and the Cauchy problem for Hamiltonian PDEs in the small dispersion limit
Davide Masoero, Andrea Raimondo
We introduce a deformation of the method of characteristics valid for Hamiltonian perturbations of a scalar conservation law in the small dispersion limit. Our method of analysis i…
On the spectrum of deformations of compact double-sided flat hypersurfaces
Denis Borisov, Pedro Freitas
We study the asymptotic behaviour of the eigenvalues of the Laplace-Beltrami operator on a compact hypersurface in \mathds{R}^{n+1} as it is flattened into a singular double-sided…
A symplectic extension map and a new Shubin class of pseudo-differential operators
Nuno Costa Dias, Maurice A. de Gosson, João Nuno Prata
For an arbitrary pseudo-differential operator with Weyl symbol $a\in\mathcal{S}^{\prime}(\mathb…
On the metric operator for the imaginary cubic oscillator
Petr Siegl, David Krejcirik
We show that the eigenvectors of the PT-symmetric imaginary cubic oscillator are complete, but do not form a Riesz basis. This results in the existence of a bounded metric operator…
Painleve I, Coverings of the Sphere and Belyi Functions
Davide Masoero
The theory of poles of solutions of Painleve-I is equivalent to the Nevanlinna problem of constructing a meromorphic function ramified over five points - counting multiplicities -…
From simplicial Chern-Simons theory to the shadow invariant II
Atle Hahn
This is the second of a series of papers in which we introduce and study a rigorous "simplicial" realization of the non-Abelian Chern-Simons path integral for manifolds M of the fo…

This is the first of a series of papers in which we introduce and study a rigorous "simplicial" realization of the non-Abelian Chern-Simons path integral for manifolds M of the for…
Planetary motion on an expanding locally anisotropic background
P. Castelo Ferreira
In this work are computed analytical solutions for orbital motion on a background described by an Expanding Locally Anisotropic (ELA) metric ansatz. This metric interpolates betwee…
Asymptotic Properties of Coupled Forward-Backward Stochastic Differential Equations
Ana Bela Cruzeiro, André de Oliveira Gomes, Liangquan Zhang
In this paper, we consider coupled forward-backward stochastic differential equations (FBSDEs in short) with parameter . We study the asymptotic behavior of its sol…
Constraining an Expanding Locally Anisotropic metric from the Pioneer anomaly
P. Castelo Ferreira
It is discussed the possibility of a fine-tuneable contribution to the two way Doppler acceleration either towards, either outwards the Sun for heliocentric distances above 20 AU b…
Noncanonical Phase-Space Noncommutative Black Holes
Catarina Bastos, Orfeu Bertolami, Nuno Dias +1
In this contribution we present a noncanonical phase-space noncommutative (NC) extension of a Kantowski Sachs (KS) cosmological model to describe the interior of a Schwarzschild bl…
