Theorems in algebraic geometry

Projection formula

In algebraic geometry, the projection formula states the following: For a morphism of ringed spaces, an -module and a locally free -module of finite rank, the natural maps of sheaves are isomorphisms. There is yet another projection formula in the setting of étale cohomology. (Wikipedia).

Multivariable Calculus | The projection of a vector.

We define the projection of a vector in a certain direction. As an application we decompose a vector into the sum of a parallel and orthogonal component. http://www.michael-penn.net http://www.randolphcollege.edu/mathematics/

Zakhar Kabluchko: Random Polytopes, Lecture III

In these three lectures we will provide an introduction to the subject of beta polytopes. These are random polytopes defined as convex hulls of i.i.d. samples from the beta density proportional to (1 − ∥x∥2)β on the d-dimensional unit ball. Similarly, beta’ polytopes are defined as convex
