Theta Functions Course
Dive deep into theta functions, starting with series convergence and moving to modular transformations and elliptic functions. Construct explicit models via theta quotients, link them to the Weierstrass ℘-function, and discover their vital roles in elliptic curves, modular forms, and physics applications, all with rigorous proofs and practical examples.

What will I learn?
This course guides you from basic theta function definitions and convergence through vital functional equations, transformation rules, and quasi-periodic properties. You'll encode lattices, build elliptic functions using theta quotients, connect them to the Weierstrass ℘-function, and use uniqueness and dimension theorems, complete with solid proofs, examples, and tips for clear, precise writing and proper referencing.
