Optimal control for cooperative systems involving fractional Laplace operators

open access: yesJournal of Inequalities and Applications, 2021
In this work, the elliptic 2 × 2 $2\times 2$ cooperative systems involving fractional Laplace operators are studied. Due to the nonlocality of the fractional Laplace operator, we reformulate the problem into a local problem by an extension problem. Then,

Convex KKM maps, monotone operators and Minty variational inequalities

open access: yes, 2015
It is known that for convex sets, the KKM condition is equivalent to the finite intersection property. We use this equivalence to obtain a characterisation of monotone operators in terms of convex KKM maps and in terms of the existence of solutions to ...

Hierarchical convergence of an implicit double-net algorithm for nonexpansive semigroups and variational inequality problems

open access: yes, 2011
In this paper, we show the hierarchical convergence of the following implicit double-net algorithm: xs,t=s[tf(xs,t)+(1-t)(xs,t-μAxs,t)]+(1-s)1λs∫0λsT(v)xs,tdν,∀s,t∈(0,1), where f is a ρ-contraction on a real Hilbert space H, A : H → H is an α-inverse ...

Principal eigenvalue characterization connected with stochastic particle motion in a finite interval

open access: yesInternational Journal of Stochastic Analysis, Volume 15, Issue 4, Page 349-356, 2002., 2002
In this paper, we show that despite their distinction, both the Statonovich and Îto s calculi lead to the same reactive Fokker‐Planck equation: ∂p∂t−∂∂x[D∂p∂x−bp]=λmp, (1) describing stochastic dynamics of a particle moving under the influence of an indefinite potential m(x, t), a drift b(x, t), and a constant diffusion D.

On a Class of Elliptic Equations for the N-Laplacian in R^n with One-Sided Exponential Growth [PDF]

open access: yes, 2003
2000 Mathematics Subject Classification: 35J40, 49J52, 49J40, 46E30By means of a suitable nonsmooth critical point theory for lower semicontinuous functionals we prove the existence of infinitely many solutions for a class of quasilinear Dirichlet ...

Dynamics of screw dislocations: a generalised minimising-movements scheme approach [PDF]

open access: yes, 2015
The gradient flow structure of the model introduced in [CG99] for the dynamics of screw dislocations is investigated by means of a generalised minimising-movements scheme approach. The assumption of a finite number of available glide directions, together

Characterizations of weak-ANODD set-valued mappings with applications to an approximate solution of GNMOQV inclusions involving ⊕ operator in ordered Banach spaces

open access: yes, 2013
In ordered Banach spaces, characterizations of ordered (αA,λ)-weak-ANODD set-valued mappings are introduced and studied, which is applied to giving an approximate solution for a new class of general nonlinear mixed-order quasi-variational inclusions ...

Mixed variational inequalities and economic equilibrium problems

open access: yesJournal of Applied Mathematics, Volume 2, Issue 6, Page 289-314, 2002., 2002
We consider rather broad classes of general economic equilibrium problems and oligopolistic equilibrium problems which can be formulated as mixed variational inequality problems. Such problems involve a continuous mapping and a convex, but not necessarily differentiable function. We present existence and uniqueness results of solutions under weakened P‐

Total destruction of invariant tori for the generalized Frenkel-Kontorova model

open access: yes, 2011
We consider generalized Frenkel-Kontorova models on higher dimensional lattices. We show that the invariant tori which are parameterized by continuous hull functions can be destroyed by small perturbations in the $C^r$ topology with ...

Solving GNOVI frameworks involving (γG,λ)-weak-GRD set-valued mappings in positive Hilbert spaces

open access: yes, 2014
First, a new concept, positive Hilbert spaces, is introduced and some fundamental inequalities which are applied to studying the properties of the resolvent operator associated for (γG,λ)-weak-GRD set-valued mappings are introduced and discussed in ...
