Theta Functions Course
Dive into theta functions, covering series convergence, key identities, modular transformations, and their role in elliptic functions. Construct theta-quotient representations, explore connections to the Weierstrass ℘-function, and discover applications in elliptic curves, modular forms, and physics, with rigorous proofs and examples for deep understanding.

What will I learn?
This course provides a structured journey through theta functions, starting from fundamental definitions and convergence properties, progressing to essential functional equations, transformation laws, and quasi-periodic behaviours. Participants will learn to represent lattices, develop elliptic functions using theta quotients, connect them to the Weierstrass ℘-function, and utilise uniqueness and dimension theorems, supported by detailed proofs, practical examples, and tips for accurate, rigorous writing and proper referencing.
