چکیده

The recently introduced proximal average of two convex functions is a convex function with many useful properties. In this paper, we introduce and systematically study the proximal average for finitely many convex functions. The basic properties of the proximal average with respect to the standard convex-analytical notions (domain, Fenchel conjugate, subdifferential, proximal mapping, epi-continuity, and others) are provided and illustrated by several examples. 2000 Mathematics Subject Classification: Primary 90C25; Secondary 26A51, 26B25, 26E60, 46C05, 47H05, 52A41.

A Proximal Average for Nonconvex Functions: A Proximal Stability Perspective

Bauschke, Lucet, and Trienis [SIAM Rev., 50 (2008), pp. 115–132] developed the concept of the proximal average of two convex functions. In this work we show the relationship between the proximal average and the Moreau envelope and exploit this relationship to develop stability theory for a generalized proximal average function. This approach allows us to extend the concept of the proximal avera...

Impact of group sexual counseling based on the self-determination theory on women’s sexual function

Background & Aim: Sexual function is an important part of the health of women, and the satisfaction of basic psychological needs is among the variables related to sexual dysfunction. The self-determination theory is one of the most important motivational theories, which considers one’s internal motive the main cause of behavior, and also views three psychological needs (autonomy, relatedness, a...

Collaborative L2 Interactivity in Diverse ZPD-Based Proximal Contexts and Interactional Competence Development

Central to Vygotsky-inspired sociocultural theory (SCT) is the notion of ZPD seen by SLA researchers as a useful framework within which L2 teaching and learning can take place. Van Lier (2004) argues that the ZPD could be activated in diverse proximal contexts (PCs) and is not limited to the expert-novice scenario. . This study probed whether Iranian EFL learners' collaborative task performance...

The Outcome of Proximal Humeral Locking Plates in the Management of Three and Four Part Proximal Humeral Fractures in Special Cohort of Young Patients in High Velocity Trauma

Background: Locking plate fixation provides satisfactory outcome following proximal humerus fractures. None of theprevious studies selectively evaluate the outcome in young patients. This study evaluates outcome of locking platesystem in the treatment of acute three- and four-part fractures in young patients.Methods: In this prospective study we included all patients who were less than 60 years...
