What is Single and Multivalued Complex Functions about?
1. Single-valued functions like exponential, hyperbolic, trigonometric, and logarithmic functions can be defined via power series that converge in the entire complex plane, making them analytic everywhere. 2. Multivalued functions have two or more distinct values for each value of the variable. Important examples include square roots, nth roots, logarithms, and inverse trigonometric functions. 3. To make multivalued functions single-valued, one must select a "branch" or sheet and define cuts or branches
