Labeled negative lens diverging the light rays passing through the lens from an axis and convex lens converges the light rays passing through the lens to a point. The convex or biconvex lens is ...

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 problems and difficulty level of the ...

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 a previous paper, we showed that gradient maps of exponentially concave functions provide solutions to a Monge–Kantorovich optimal transport problem and give a better gradient approximation than ...

In this paper, we propose a distributed stochastic first-order method for saddle point problems over strongly connected graphs. Existing methods generally suffe ...
