# Interactive video lesson plan for: Mod-01 Lec-04 A Riemann Surface Structure on a Cylinder

#### Activity overview:

An Introduction to Riemann Surfaces and Algebraic Curves: Complex 1-Tori and Elliptic Curves by Dr. T.E. Venkata Balaji, Department of Mathematics, IIT Madras. For more details on NPTEL visit http://www.nptel.iitm.ac.in/syllabus/111106044/

Goals of the Lecture:

- To interpret a cylinder as a suitable quotient of the complex plane;
- To use the above interpretation to give a Riemann surface structure on a cylinder and
to raise the question as to how many such non-isomorphic structures exist.

Keywords for Lecture 4:

Translation by a complex number, equivalence relation, equivalence class, set modulo an equivalence relation, glueing edges of a strip, inverse image of an equivalence class, quotient topology, quotient map, open map, homeomorphism, Moebius transformation, group action on a set, orbits of an action, set modulo (action of) a group

@kklaster

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

@ordmiss

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral
