Federer Geometric Measure Theory Pdf |best|

Herbert Federer’s Geometric Measure Theory (1969) is widely regarded as the definitive, encyclopedic treatise on the subject, serving as an essential reference for modern analysts and researchers. The book unified several branches of mathematics—including multilinear algebra, measure theory, and algebraic topology—to provide a rigorous framework for solving geometric variational problems, most notably the "least area" or minimal surface problem.

Chapter 5 – Deformation Theorem and Compactness

• Homotopy formulas for currents.
• The Federer‑Fleming deformation theorem (approximating a current by polyhedral chains).
• Compactness in the flat norm and mass norm.
