The coronavirus disease-2019 (COVID-19) epidemic started in late 2019, and was upgraded to a pandemic on March 11, 2020 by the World Health Organization (WHO). Well established epidemiological models have been used over the last few months in an atte

We examine to what extent finite-dimensional spaces defined on locally compact subsets of the line and possessing various weak Chebyshev properties (involving sign changes, zeros, alternation of best approximations, and peak points) can be uniformly

We describe in this paper a spectrum of inequalities obtained through the use of total positivity methods mostly motivated by models of biological evolutionary processes, by problems originating in probability and statistical context, and by challeng

The concept of a generalized completely convex function is extended arid a unified presentation is developed for expanding such functions by Taylor–Lidstone series. It is shown that these expansions are in fact tantamount to representation theorems

The relationship between various types of Korovkin shadows is explored. An intrinsic characterization of Korovkin subspaces and Korovkin shadows is given. For some cases the detailed structure of the Korovkin shadows is presented.

Let M be a normed linear space, and {Mn}1∞ a sequence of increasing finite dimensional subspaces, i.e., Mn ⊂ Mn + 1, for all n. For any element ƒ ϵ M, we obviously have d(ƒ, Mn) ⩾ d(ƒ, Mn + 1), for all n, (1) where d(ƒ, Mk) is the distance
