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 ...

The theory of second-order epi-derivatives of extended-real-valued functions is applied to convex functions on $\mathbb{R}^n$ and shown to be closely tied to proto-differentiation of the corresponding ...

Difference between Concave vs Convex Lens: Isn’t physics one of those subjects that almost every student is scared of? Well why not, given the complexity of ...
