Well-posedness and invariant measures for HJM models with deterministic volatility and Lévy noise
We give sufficient conditions for existence, uniqueness and ergodicity of invariant measures for Musiela's stochastic partial differential equation with deterministic volatility and a Hilbert space valued driving Lévy ...

Exponentially small splitting of separatrices in the perturbed McMillan map
The McMillan map is a one-parameter family of integrable symplectic maps of the plane, for which the origin is a hyperbolic fixed point with a homoclinic loop, with small Lyapunov exponent when the parameter is small. We ...
Discontinuous Galerkin methods for the one-dimensional Vlasov-Poisson system
We construct a new family of semi-discrete numerical schemes for the approximation of the one-dimensional periodic Vlasov-Poisson system. The methods are based on the coupling of discontinuous Galerkin approximation to the ...
A model structure for coloured operads in symmetric spectra
We describe a model structure for coloured operads with values in the category of symmetric spectra (with the positive model structure), in which fibrations and weak equivalences are defined at the level of the underlying ...
On the asymptotic expansion of the colored Jones polynomial for torus knots
In the asymptotic expansion of the hyperbolic specification of the colored Jones polynomial of torus knots, we identify different geometric contributions, in particular Chern-Simons invariant and Reidemeister torsion.
Krein's strings whose spectral functions are of polynomial growth
In case Krein's strings with spectral functions of polynomial growth a necessary and su fficient condition for the Krein's correspondence to be continuous is given.
On the analysis of travelling waves to a nonlinear flux limited reaction-diffusion equation
In this paper we study the existence and qualitative properties of travelling waves associated to a nonlinear flux limited partial differential equation coupled to a Fisher-Kolmogorov-Petrovskii-Piskunov type reaction term. ...

Net spaces and boundedness of integral operators
In this paper we introduce new functional spaces which we call the net spaces. Using their properties, the necessary and sufficient conditions for the integral operators to be of strong or weak-type are obtained. The ...
Mather invariants in groups of piecewise-linear homeomorphisms
We describe the relation between two characterizations of conjugacy in groups of piecewise-linear homeomorphisms, discovered by Brin and Squier in [2] and Kassabov and Matucci in [5]. Thanks to the interplay between the ...

Improving Accessibility to Radiotherapy Services in Cali, Colombia : Cross-Sectional Equity Analyses Using Open Data and Big Data Travel Times from 2020
In this study, we employed a methodology to evaluate and forecast the cumulative opportunities for residents to access radiotherapy services in Cali, Colombia, while accounting for traffic congestion from an equity ...

Merging of superfluid Helium nanodroplets with vortices
Within Density Functional Theory, we have investigated the coalescence dynamics of two superfluid helium nanodroplets hosting vortex lines in different relative orientations, which are drawn towards each other by the Van ...
