Mode Decomposition Evolution Equations [PDF]

open access: yesJournal of Scientific Computing, 2011
Partial differential equation (PDE) based methods have become some of the most powerful tools for exploring the fundamental problems in signal processing, image processing, computer vision, machine vision and artificial intelligence in the past two decades. The advantages of PDE based approaches are that they can be made fully automatic, robust for the

Controllability of Evolution Equations with Memory [PDF]

open access: yesSIAM Journal on Control and Optimization, 2017
This article is devoted to studying the null controllability of evolution equations with memory terms. The problem is challenging not only because the state equation contains memory terms but also because the classical controllability requirement at the final time has to be reinforced, involving the contribution of the memory term, to ensure that the ...

Attractors for a class of semi-linear degenerate parabolic equations [PDF]

open access: yes, 2013
We consider degenerate parabolic equations of the form ∂tu = Δλu + f(u) u|∂Ω = 0, u|t=0 = u0 in a bounded domain Ω ⊂N, where Δλ is a subelliptic operator of the type (Formula presented.) We prove global existence of solutions and characterize their ...

Particle Production at High Energy: DGLAP, BFKL and Beyond

open access: yesUniverse, 2019
Particle production in high energy hadronic/nuclear collisions in the Bjorken limit Q 2 , s → ∞ can be described in the collinear factorization framework of perturbative Quantum ChromoDynamics (QCD). On the other hand in the Regge

Dependence on the Initial Data for the Continuous Thermostatted Framework

open access: yesMathematics, 2019
The paper deals with the problem of continuous dependence on initial data of solutions to the equation describing the evolution of a complex system in the presence of an external force acting on the system and of a thermostat, simply identified with the ...

Smoothing properties for Hirota-Satsuma systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
We study local existence and smoothing properties for the initial value problem associated to Hirota-Satsuma systems that describes an interaction of two long waves with different dispersion relations.

Gradient flows for bounded linear evolution equations [PDF]

open access: yes, 2021
We study linear evolution equations in separable Hilbert spaces defined by a bounded linear operator. We answer the question which of these equations can be written as a gradient flow, namely those for which the operator is real diagonalisable. The proof

Modelling the evolution of the two-planetary three-body system of variable masses

open access: yesMathematical Modelling and Analysis, 2023
A classical non-stationary three-body problem with two bodies of variable mass moving around the third body on quasi-periodic orbits is considered. In addition to the Newtonian gravitational attraction, the bodies are acted on by the reactive forces ...
