Journal of Applied Mathematics, Volume 2004, Issue 5, Page 409-431, 2004., 2004 We consider the problem of projecting a point onto a region defined by a linear equality or inequality constraint and two‐sided bounds on the variables. Such problems are interesting because they arise in various practical problems and as subproblems of gradient‐type methods for constrained optimization.

Complex quadratic optimization and semidefinite programming [PDF]
, 2006 . In this paper we study the approximation algorithms for a class of discrete quadratic optimization problems in the Hermitian complex form. A special case of the problem that we study corresponds to the max-3-cut model used in a recent paper of Goemans ...

On the closure of the sum of closed subspaces
International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 5, Page 257-267, 2001., 2001 We give necessary and sufficient conditions for the sum of closed subspaces of a Hilbert space to be closed. Specifically, we show that the sum will be closed if and only if the angle between the subspaces is not zero, or if and only if the projection of either space into the orthogonal complement of the other is closed.

On a class of multivalued variational inequalities
International Journal of Stochastic Analysis, Volume 11, Issue 1, Page 79-93, 1998., 1996 In this paper, we introduce and study a new class of variational inequalities, which are called multivalued variational inequalities. These variational inequalities include as special cases, the previously known classes of variational inequalities. Using projection techniques, we show that multivalued variational inequalities are equivalent to fixed ...

On certain classes of variational inequalities and related iterative algorithms
International Journal of Stochastic Analysis, Volume 9, Issue 1, Page 43-56, 1996., 1995 In this paper, we introduce and study some new classes of variational inequalities and Wiener‐Hopf equations. Essentially using the projection technique, we establish the equivalence between the multivalued general quasi‐variational inequalities and the multivalued implicit Wiener‐Hopf equations.

The role of child language ability and parental mentalization in early child dysregulation
Infant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 1, January 2026.Abstract Dysregulation in early childhood is associated with increased vulnerability to psychopathology and poor psychosocial outcomes. While there is evidence that both child language ability and parental mentalization are associated with dysregulation in early childhood, there is little understanding of the relationships between these variables, and ...
