Abel–Goncharov interpolation

Abel–Goncharov interpolation is a mathematical technique that combines concepts from various fields, including complex analysis, function theory, and interpolation theory. The technique is named after mathematicians Niels Henrik Abel and A. A. Goncharov and extends the basic idea of interpolation to handle problems where traditional polynomial interpolation may not be effective or applicable. ### Key Concepts: 1. **Abel's Theorem**: Abel's theorem is a fundamental result in the theory of series and functions.
