Global and local reduced models for interacting, heterogeneous agents. [PDF]

Chaos, 2021
Large collections of coupled, heterogeneous agents can manifest complex dynamical behavior presenting difficulties for simulation and analysis. However, if the collective dynamics lie on a low-dimensional manifold, then the original agent-based model may

Analysis of dynamical behaviour of full-floating disk thrust bearings

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023
. Full-floating ring bearings are state of the art at high speed turbomachinery shafts like in turbochargers. Their main feature is an additional ring between shaft and housing leading to two fluid films in serial arrangement.

A First-order Two-scale Analysis for Contact Problems with Small Periodic Configurations [PDF]

, 2019
This paper is devoted to studying a type of contact problems modeled by hemivariational inequalities with small periodic coefficients appearing in PDEs, and the PDEs we considered are linear, second order and uniformly elliptic. Under the assumptions, it

Lie symmetries of a third order PDE system [PDF]

arXiv, 2021
In this paper we show that a third order PDE system that is a general form of a CR-geometry PDE system has at most a ten-dimensional Lie symmetry algebra. We also show that this estimate is precise.

An elliptic pde with convex solutions [PDF]

arXiv, 2014
Using a mixture of classical and probabilistic techniques we investigate the convexity of solutions to the elliptic pde associated with a certain generalized Ornstein-Uhlenbeck process.

Arnold-Liouville theorem for integrable PDEs: a case study of the focusing NLS equation [PDF]

arXiv, 2020
We prove an infinite dimensional version of the Arnold-Liouville theorem for integrable non-linear PDEs: In a case study we consider the {\em focusing} NLS equation with periodic boundary conditions.

Costruction of classic exact solutions for Tricomi equation [PDF]

arXiv, 2010
A formula to construct classic exact solutions to Tricomi partial differential equation. The steps to obtain this formula require only elementary resolution of a simple system of first order PDEs.
