Modulus and characteristic of convexity

In mathematics, the modulus of convexity and the characteristic of convexity are measures of "how convex" the unit ball in a Banach space is. In some sense, the modulus of convexity has the same relationship to the ε-δ definition of uniform convexity as the modulus of continuity does to the ε-δ definition of continuity. (Wikipedia).

What is the difference between convex and concave polygons

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1

Yakov Eliashberg - Interplay between notions of convexity in complex, symplectic and contact (...)

The classical notions of holomorphic, polynomial, rational convexity, and pseudo-convexity in complex geometry have their counterparts in symplectic and contact geometries. Understanding the relationship between these notions is important for all these fields. Yakov Eliashberg (Stanford)
