On Two Iterative Methods for Mixed Monotone Variational Inequalities

open access: yesFixed Point Theory and Applications, 2010
A mixed monotone variational inequality (MMVI) problem in a Hilbert space H is formulated to find a point u∗∈H such that 〈Tu∗,v−u∗〉+φ(v)−φ(u∗)≥0 for all v∈H ...

Iterative methods for zero points of accretive operators in Banach spaces

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
The purpose of this paper is to consider the problem of approximating zero points of accretive operators. We introduce and analysis Mann-type iterative algorithm with errors and Halpern-type iterative algorithms with errors.

Duality for nonsmooth mathematical programming problems with equilibrium constraints

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we consider the mathematical programs with equilibrium constraints (MPECs) in Banach space. The objective function and functions in the constraint part are assumed to be lower semicontinuous.

Market Making With Fads, Informed, and Uninformed Traders

open access: yesMathematical Finance, EarlyView.
ABSTRACT We characterize the solution to a continuous‐time optimal liquidity provision problem in a market populated by informed and uninformed traders. In our model, the asset price exhibits fads —these are short‐term deviations from the fundamental value of the asset.

A viability result for second-order differential inclusions

open access: yesElectronic Journal of Differential Equations, 2002
We prove a viability result for the second-order differential inclusion $$ x''in F(x,x'),quad (x(0), x'(0))=(x_0,y_0)in Q:=Kimes Omega, $$ where $K$ is a closed and $Omega$ is an open subsets of $mathbb{R}^m$, and is an upper semicontinuous set-valued ...

Risk Measure Duality Without Structure

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study risk measures on vector spaces of random variables which a priori have little structure, such as spaces lacking law invariance or a lattice structure. Ensuring the existence of a tractable dual representation (one which does not contain non‐sigma‐additive measures) is one of the main problems in risk measure theory, and we address it ...

Radial representation of lower semicontinuous envelope

open access: yes, 2014
We give an extension to a nonconvex setting of the classical radial representation result for lower semicontinuous envelope of a convex function on the boundary of its effective domain.

MRpro: Open Framework for Model‐Based, Learned, and Quantitative MR Imaging—Application to Low‐Field MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 11, November 2026.
MRpro is an open‐source PyTorch framework for MR image reconstruction and quantitative parameter estimation. Its modular design combines standardized data handling, composable operators, ready‐to‐use algorithms, and deep‐learning components to support reproducible workflows for conventional and low‐field MRI.

Lower semicontinuity for an integral functional in BV [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2016
We prove a lower semicontinuity result for a functional of linear growth initially defined by \[ \int_ΩF\left(\frac{dDu}{dμ}\right)\,dμ\] for $u\in BV(Ω;\mathbb{R}^N)$ with $Du\ll μ$. The positive Radon measure $μ$ is only assumed to satisfy $\mathcal L^n\ll μ$.

Existence and uniqueness of anti-periodic solutions for nonlinear third-order differential inclusions

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we study the existence of anti-periodic solutions for the third-order differential inclusion $$displaylines{ u'''(t)in partialvarphi(u'(t))+F(t,u(t))quad hbox{a.e.
