Complex analysis
Holomorphic functions, contour integrals, and residues.
- Holomorphic functions & power seriesComplex differentiability in a neighborhood is far more rigid than real differentiability.
- Contour integration & Cauchy formulasContour integrals connect local values of a holomorphic function to its behavior around a boundary.
- Laurent series, poles & residuesThe coefficient of (z−a)⁻¹ records the local contribution to a contour integral.
