Cauchy-Lipschitz theory for fractional multi-order dynamics: State-transition matrices, Duhamel formulas and duality theorems [PDF]

open access: greenDifferential and Integral Equations, 2018
The aim of the present paper is to contribute to the development of the study of Cauchy problems involving Riemann-Liouville and Caputo fractional derivatives. Firstly existence-uniqueness results for solutions of non-linear Cauchy problems with vector fractional multi-order are addressed. A qualitative result about the behavior of local but non-global

The Approximate Duality Gap Technique: A Unified Theory of First-Order Methods [PDF]

open access: greenSIAM Journal on Optimization, 2019
We present a general technique for the analysis of first-order methods. The technique relies on the construction of a duality gap for an appropriate approximation of the objective function, where the function approximation improves as the algorithm converges.

Gravitational radiation from color-kinematics duality [PDF]

open access: yesJournal of High Energy Physics, 2018
We perturbatively calculate classical radiation in Yang-Mills theory and dilaton gravity, to next-to-leading order in couplings. The radiation is sourced by the scattering of two relativistic massive scalar sources with the dynamical effect taken into ...

On duality theory for multiobjective semi-infinite fractional optimization model using higher order convexity [PDF]

open access: hybridRAIRO - Operations Research, 2021
In the article, a semi-infinite fractional optimization model having multiple objectives is first formulated. Due to the presence of support functions in each numerator and denominator with constraints, the model so constructed is also non-smooth. Further, three different types of dual modelsvizMond-Weir, Wolfe and Schaible are presented and then usual

An uplifting discussion of T-duality

open access: yesJournal of High Energy Physics, 2018
It is well known that string theory has a T-duality symmetry relating circle compactifications of large and small radius. This symmetry plays a foundational role in string theory.

Duality theory forN-th order differential operators under stieltjes boundary ponditions. II: Nonsmooth coefficients and nonsingular measures [PDF]

open access: bronzeAnnali di Matematica Pura ed Applicata, 1975
Adjoint relations are characterized for an n-th order vector valued differential system with nonsmooth coefficients and with boundary conditions represented by Stieltjes measures of bounded variation when the system is viewed as an operator with domain and range in a space of Lp integrable functions.

Super-duality and necessary optimality conditions of order "infinity" in optimal control theory [PDF]

open access: green
We systematically introduce an approach to the analysis and (numerical) solution of a broad class of nonlinear unconstrained optimal control problems, involving ordinary and distributed systems. Our approach relies on exact representations of the increments of the objective functional, drawing inspiration from the classical Weierstrass formula in ...
