METRIC PROJECTIONS IN LINEAR METRIC SPACES
Summary: Various properties of the metric projection are known in normed linear spaces. \textit{G. Pantelidis} [Math. Ann. 184, 30--48 (1969; Zbl 0175.42001)] discussed some of these properties in linear metric spaces. In this paper we also discuss some necessary and sufficient conditions for the metric projections to be continuous and Lipschitzian in ...

Metric projections and the alternating projection method in banach spaces
This thesis is concerned with properties of the metric projection and its iterates in Banach spaces. It extends a result by Stiles concerning the convergence behaviour of the alternating projection method from finite-dimensional spaces to some infinite ...

On the Norm of the Metric Projections
Let \(X\) be a Banach space and \(M\) a subspace of \(X\). Define \[ P_M(x)= \{y\in M:\| x-y\|= d(x,M)\}. \] The set-valued mapping \(P_M:X\to 2^M\), thus defined is called the metric projection onto \(M\). The space \(M\) is called proximinal if \(P_M(x)\neq \emptyset\) for every \(x\in X\). The norm of \(P_M\) is defined by \[ \| P_M\|= \sup\{\| y\|:

ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Approximate Common Solutions for a Family of Inverse Strongly Monotone Mappings
In 2003 W. Takahashi and M. Toyoda showed the weak convergence of an iteration process of finding the solution of a variational inequality problem for an inverse strongly monotone mapping.

ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
