👉 The term "plangent" refers to a specific type of mathematical object that is used in the study of differential equations and complex analysis. In mathematics, a plangent is an element of a certain class of functions known as meromorphic functions. Meromorphic functions are holomorphic functions whose poles are simple (i.e., the set of points where they occur) but which do not have any essential singularities (singularities that can be removed by analytic continuation).
