We present an alternative proof of the Mountain Pass Theorem by means of the classical Ekeland Variational Principle for a class of <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${\mathcal{C}^1}$$</EquationSource> </InlineEquation> -functionals. In this new proof we avoid the machinery of convex analysis by a simpler characterization of the critical values of the...</equationsource></inlineequation>

We present an application of a novel Variational Wave Acquisition Stereo System (VWASS) for the estimation of the wave surface height of oceanic sea states. Specifically, we show that VWASS video technology combined with statistical techniques based on Euler Characteristics of random fields...

We study the almost periodic solutions of Euler equations and of some more general difference equations. We consider two different notions of almost periodic sequences, and we establish some relations between them. We build suitable sequences spaces and we prove some properties of these spaces....
