Following the basic principles stated by Painlevé, we first revisit the process of selecting the admissible time-independent Hamiltonians H = (p12 + p22)/2
In this paper we establish a result about uniformly equivalent norms and the convergence of best approximant pairs on the unitary ball for a family of weighted
There are mainly two approaches to the multifractal analysis of measures.The first one,which is used in applications and in studying problems arising from dynam
