Elliptic curves belong to the
most fundamental objects in mathematics and connect many different research
areas such as number theory, algebraic geometry and complex analysis. Their
definition and basic properties can be stated in an elementary way: Roughly
speaking, an elliptic curve is the set of solutions to a cubic equation in
two variables over a field. This PDF covers the following topics related to
