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.

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.

This video follows on from DiffGeom21: An Introduction to surfaces, starting with ruled surfaces. These were studied by Euler, and Monge gave examples of how such surfaces arose from the study of curves, namely as polar developables. A developable surface is a particularly important and us

What Is Surface Anatomy?

In the first mini-lecture, we ask the question: what is surface anatomy? We learn how anatomy is the study of the structure of our bodies, including osteology, histology, gross anatomy, imaging, embryology and indeed surface anatomy. As you might imagine, surface anatomy studies the extern

Multivariable Calculus | The tangent plane of a level surface.

We derive the equation of a plane tangent to a level surface. That is, a surface defined by the equation F(x,y,z)=k. http://www.michael-penn.net http://www.randolphcollege.edu/mathematics/

Effective mapping class group dynamics - Francisco Andres Arana Herrera

Motivated by counting problems for closed geodesics on hyperbolic surfaces, I will present a family of new results describing the dynamics of mapping class groups on Teichmüller spaces and spaces of closed curves of closed surfaces.
