An existence theorem for optimal control with nonstandard cost functionals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 10, Issue 3, Page 609-611, 1987., 1987
An existence theorem for optimal control is obtained for a general nonstandard cost functional of fractional type in this work. As an application of our result we can derive an existence theorem for optimal control given by M. B. Subrahamanyam for a cost functional, which is a ratio of two given integral cost functionals.

On solving the plateau problem in parametric form

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 6, Issue 2, Page 341-361, 1983., 1981
This paper presents a numerical method for finding the solution of Plateau′s problem in parametric form. Using the properties of minimal surfaces we succeded in transferring the problem of finding the minimal surface to a problem of minimizing a functional over a class of scalar functions.

Testing reliability and validity of practitioner‐rated parental sensitivity: A novel tool for practice

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 2, Page 234-246, March 2024.
Abstract Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e‐learning tool and an interactive decision tree provided through a mobile application, called the OK! package.

A new distributionally robust reward-risk model for portfolio optimization

open access: yesOpen Mathematics
A new distributionally robust ratio optimization model is proposed under the known first and second moments of the uncertain distributions. In this article, both standard deviation (SD) and conditional value-at-risk (CVaR) are used to measure the risk ...

The robust isolated calmness of spectral norm regularized convex matrix optimization problems

open access: yesOpen Mathematics
This article aims to provide a series of characterizations of the robust isolated calmness of the Karush-Kuhn-Tucker (KKT) mapping for spectral norm regularized convex optimization problems. By establishing the variational properties of the spectral norm

Geometric approaches to matrix normalization and graph balancing

open access: yesForum of Mathematics, Sigma
Normal matrices, or matrices which commute with their adjoints, are of fundamental importance in pure and applied mathematics. In this paper, we study a natural functional on the space of square complex matrices whose global minimizers are normal ...
