What are the names of different types of polygons based on the number of sides

👉 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

Cristina Câmara: Truncated Toeplitz operators

Abstract: Toeplitz matrices and operators constitute one of the most important and widely studied classes of non-self-adjoint operators. In this talk we consider truncated Toeplitz operators, a natural generalisation of finite Toeplitz matrices. They appear in various contexts, such as the

Modular forms: Modular functions

This lecture is part of an online graduate course on modular forms. We classify all meromorphic modular functions, showing that they are all rational functions of the elliptic modular function j. As an application of j we use it to prove Picard's theorem that a non-constant meromorphic

Poisson formula on half plane

In this video, I solve Laplace's equation on the upper half-plane. For this, I use Green's functions and a clever reflection formula. At the end, I derive the celebrated "Fish" formula for the upper half-plane. Enjoy! Green's Function: https://youtu.be/kqg8L41u4Yg Partial Differential Equ
