Limit of a function of a complex variable
Let f(z) be a single valued function defined at all points in some neighborhood of a point z. Then the limit of _{0}f(z) as z approaches z is _{0}w._{0}
Continuity f(z) is said to be continuous at z = z if
_{0}
Differentiability Let f(z) be a single valued function of the variable z then provided that the limit exist and is independent of the path along which δz → 0. |
