In this paper we give a generalization of the Lagrange mean value theorem via lower and
upper derivative, as well as appropriate criteria of monotonicity and convexity for arbitrary …

We consider a system of nonlinear PDEs in a domain with a triple phase boundary,
describing electrochemical processes in a mixed conduction, solid-oxide cathode of a fuel …

In the previous paper (Almira and Oikhberg, 2010 [4]), the authors investigated the existence
of an element x of a quasi-Banach space X whose errors of best approximation by a given …

Bulgarian solitaire is played on n cards divided into several piles; a move consists of picking
one card from each pile to form a new pile. This can be seen as a process on the set of …

Mathematical concepts are defined precisely using the language of the branch of
mathematics to which they belong. But their meaning can be enriched through different …
