Complex line integral
Function
range | L … continuously differentiable finite lines |
definiendum | ∫:L→(C→C)→K |
range | L∈L |
range | γ:[a,b]→L … parametrization |
definiendum | ∫L f(z)dz:=∫L f(γ(t))⋅γ′(t)dt |
Theorems
If f is holomorphic and two curves L1,L2 can be deformed into each other, then
∫L1f(z)dz=∫L2f(z)dz |
