What is a plane

👉 Learn essential definitions of points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A plane contains infinite number of lines. A ray is a li

Justin Curry (05/18/22): Exemplars of Sheaf Theory in TDA

In this talk I will present four case studies of sheaves and cosheaves in topological data analysis. The first two are examples of (co)sheaves in the small: (1) level set persistence and (2) decorated merge trees. The second set of examples are focused on (co)sheaves in the large: (3) unde

Schemes 9: Spec R is a locally ringed space

This lecture is part of an online algebraic geometry course on schemes, based on chapter II of "Algebraic geometry" by Hartshorne. It gives the proof that the spectrum of a ring R is a locally ringed space, by checking the sheaf property.

Hodge theory and derived categories of cubic fourfolds - Richard Thomas

Richard Thomas Imperial College London September 16, 2014 Cubic fourfolds behave in many ways like K3 surfaces. Certain cubics - conjecturally, the ones that are rational - have specific K3s associated to them geometrically. Hassett has studied cubics with K3s associated to them at the le
