Let ${\bf T}_n = {{{\bf R}_n } / {{\bf Z}_n }}$, where ${\bf R}_n$ is n-dimensional Euclidean space and ${\bf Z}_n$ is the n-dimensional lattice group, be the n-dimensional torus. We denote elements of ${\bf T}_n$ by ${\bf \theta }$, ${\bf \varphi }$, ...

We consider a system where, at each stagen ź {1, 2, ...}=N, an elementxn* is to be chosen out of a nonempty, closed, feasible regionAn in a compact semigroupX, so as to achieve a sequence $$\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{x} $$...

A starlike tree is a tree with exactly one vertex of degree greater than two. The spectral radius of a graph G, that is denoted by $$\lambda (G)$$?(G), is the largest eigenvalue of G. Let k and $$n_1,\ldots ,n_k$$n1,?,nk be some positive integers. Let $$...
