Branch Cut -- from Wolfram MathWorld A branch cut is a curve (with ends possibly open, closed, or half-open) in the complex plane across which an analytic multivalued function is discontinuous.
[複變] 請教一個簡單的branch cut觀念- 看板Math - 批踢踢實業坊 branch cut的功用就是破壞複數平面連續性，使多值函數單值化。 ex: w = z^(0.5)。 若是取R+當branch cut，則幅角只限制在[0,2pi]區域。
