SIAM Journal on Applied Mathematics, Vol. 27, No. 1 (Jul., 1974), pp. 131-137 (7 pages) A necessary condition and a sufficient condition for the pseudo-convexity of a function are given. These ...

We prove that if two level curves of a harmonic function are convex in the hyperbolic disc then all intermediate level curves are also convex. This item is part of a ...

Convex optimisation constitutes a fundamental area in applied mathematics where the objective is to identify the minimum of a convex function subject to a set of convex constraints. This framework ...
