The inverse problem of the calculus of variations for discrete systems
(IOP Publishing, 2018-04-09)
We develop a geometric version of the inverse problem of the calculus of variations for discrete mechanics and constrained discrete mechanics. The geometric approach consists of using suitable Lagrangian and isotropic ...
Lagrangian reduction of nonholonomic discrete mechanical systems
(American Institute of Mathematical Sciences, 2010-03)
In this paper we propose a process of lagrangian reduction and<br />reconstruction for nonholonomic discrete mechanical systems where the action of a continuous symmetry group makes the configuration space a principal ...
An augmented filled function for global nonlinear integer optimization
(Springer, 2020-10)
The problem of finding global minima of nonlinear discrete functions arises in many fields of practical matters. In recent years, methods based on discrete filled functions have become popular as ways of solving these sort ...
Rule of Law and Judicial Discretion: Their Compatibility and Reciprocal Limitation
(Franz Steiner Verlag, 2018-01)
The aim of this work is to throw some light upon the compatibility between the rule of law desiderata and the phenomenon of judicial discretion. In order to achieve this, first it is necessary to determine what we understand ...
On the time discretization of stochastic optimal control problems: The dynamic programming approach
(EDP Sciences, 2019-10)
In this work, we consider the time discretization of stochastic optimal control problems. Under general assumptions on the data, we prove the convergence of the value functions associated with the discrete time problems ...

On the issue that finite element discretizations violate, nodally, Clausius postulate of the second law of thermodynamics
(Springer, 2016-12)
Discretization processes leading to numerical schemes sometimes produce undesirable effects. One potentially serious problem is that a discretization may produce the loss of validity of some of the physical principles or ...
