摘要：
We discuss the function W-t(x) defined via the implicit equation W-t(x) . tan [W-t(x)] = x. which appears in certain quantum-mechanical and field-theoretic applications. We investigate its analytic structure, develop series expansions for both small and large x, and provide various techniques for its numerical evaluation in the complex plane.
