Special functions occupy a central role in mathematical analysis, bridging pure theory and practical application across diverse scientific fields. Their intrinsic properties—such as recurrence ...

This paper examines properties and interrelations of several concepts of generalized concavity. It shows that the class of functions that are both 'generalized concave' and 'generalized convex' is ...

In recent times there occur situations, especially in estimation problems in certain stochastic processes, in which the limit of the suitably normalised log-likelihood ratios is a family of mixed or ...
