Surface integrals are kind of like higher-dimensional line integrals, it's just that instead of integrating over a curve C, we are integrating over a surface S. This can be tricky, but it has lots of applications, so let's learn how to do these things! Script by Howard Whittle Watch the

Exploring Pristine Seas | Podcast | Overheard at National Geographic
National Geographic Explorer in Residence Enric Sala quit academia to explore and protect the sea. On his journey to keep the ocean pristine, he has swam with jellyfish in Palau, gone diving in the Arctic, and got acquainted with sharks at Millennium Atoll. Sala’s explorations have led to

Complex surfaces 1: Introduction
This talk is part of a series giving an informal survey of complex algebraic surfaces. We give an overview of the Enriques-Kodaira classification, with examples of most of the different types of surfaces. We conclude by giving an example of a non-algebraic surface: the Hopf surface. Furth

Henry Adams and Enrique Alvarado: An introduction to Morse theory
We give an introduction to Morse theory. Given a space equipped with a real-valued function, one can use Morse theory to produce a compact cellular model for that space. Furthermore, the cellular model reflects important properties of the function. We describe CW cell complexes, the Morse

Complex surfaces 4: Ruled surfaces
This talk gives an informal survey of ruled surfaces and their role in the Enriques classification. We give a few examples of ruled surfaces, summarize the basic invariants of surfaces, and sketch how one classifies the surfaces of Kodaira dimension minus infinity.

Derived categories of cyclic covers and their branch divisors - Alexander Perry
Alexander Perry Harvard University April 29, 2015 Given a variety YY with a rectangular Lefschetz decomposition of its derived category, I will discuss an interesting relation between the derived categories of a cyclic cover of YY and its branch divisor. As examples, I will describe the c

Complex surfaces 5: Kodaira dimension 0
This talk is an informal survey of the complex projective surfaces of Kodaira number 0. We first explain why there are 4 types of such surfaces (Enriques, K3, hyperelliptic, and abelian) and then give a few examples of each type.

Davesh Maulik - Stable Pairs and Gopakumar-Vafa Invariants 4/5
In the first part of the course, I will give an overview of Donaldson-Thomas theory for Calabi-Yau threefold geometries, and its cohomological refinement. In the second part, I will explain a conjectural ansatz (from joint work with Y. Toda) for defining Gopakumar-Vafa invariants via modul

MATH331: Riemann Surfaces - part 1
We define what a Riemann Surface is. We show that PP^1 is a Riemann surface an then interpret our crazy looking conditions from a previous video about "holomorphicity at infinity" as coming from the definition of a Riemann Surface.

Complex surfaces 6: Kodaira dimensions 1 and 2
In this lecture we continue the overview of complex projective urfaces by discussing those of Kodaira dimensions 1 and 2. The surfaces of dimension 1 are all elliptic surfaces with a map onto a curve whose fibers are mostly elliptic curves. We describe Kodaira's classification of the poss

Sofia Tirabassi: Fourier-Mukai partners of canonical covers in positive characteristic
Abstract: We show that surfaces arising as canonical covers of Enriques and bielliptic surfaces do not have any non-trivial FourierMukai partner, extending result of Sosna for complex surfaces. This is a joint work with K. Honigs and L. Lombardi. Recording during the thematic meeting: "H
