This is the main event. Skip the rest if you have to. Read definitions 4.1.1–4.1.13 slowly. Draw terrible pictures. The key result: rectifiable sets have an integer-valued density almost everywhere (Theorem 4.3.2). That density is the "multiplicity" – your surface can cover itself, but in a measurable way.

One of the most beautiful results in the book (Theorem 3.2.3 in my edition – double-check that) is the : federer geometric measure theory pdf

Federer’s book provided the rigorous language for all of these fields. This is the main event

Herbert Federer was an Austrian-American mathematician who spent much of his career at Brown University. Along with Wendell Fleming, he helped lay the foundations of what we now call Geometric Measure Theory (GMT). Published in 1969 as part of the prestigious Grundlehren der mathematischen Wissenschaften series, his book was the first comprehensive treatment of the subject. Draw terrible pictures
