Meromorphic functions that share three limit values with their derivatives

Let f be a transcendental meromorphic function in the complex plane. We prove that if f and \(f'\) $f^{\prime }$ share three finite limit values, then f and \(f'\) $f^{\prime }$ share all limit values. If f is entire, two finite shared limit values with \(f'\) $f^{\prime }$ give the same conclusion.
