Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...

Functional differential equations with forward and backward delays arise naturally, for instance, in the study of travelling waves in lattice equations and as semi-discretizations of partial ...

This paper is concerned with the problem of nonlinear best simultaneous approximations in Köthe Bochner function spaces with respect to Minkowski’ norms in Euclidean spaces. Characterization results ...
