Question: In mathematics, the Borel–Carathéodory theorem in complex analysis shows that an analytic function may be bounded by its real part, it is named for Émile Borel and Constantin Carathéodory, was a Greek mathematician who spent most of his professional career in which country?
Sentence (from "Monodromy theorem"): The idea is that one can extend a complex-analytic function (from here on called simply "analytic function") along curves starting in the original domain of the function and ending in the larger set.
Relevant evidence: No
