👉 In mathematics, an "ephemeromorphic function" is a type of meromorphic function that can be defined on a domain containing only simple poles and zeros. These functions are particularly useful in physics and engineering for modeling systems with time-dependent inputs or outputs.
Ephemeromorphic functions have the form:
f(z) = f(a + zb) + (1/b)
f(a - zb)
where a is a complex number, b is a real number, and f(z) is
