moving-frames proof of the Gauss–Bonnet theorem, complete with a care-ful treatment of Hopf’s rotation angle theorem (the Umlaufsatz). Chapter 10 is largely of a technical nature, covering Jacobi fields, conjugate points, the second variation formula, and the index form for later use in com-parison theorems.

Inequalities of Analysis - University of Utah

Theorem The area of a triangle with given perimeter 2p = a+b+c is maximum if the sides a, b, c are equal. Proof. For a nondegenerate triangle, the sum of the lengths of any two sides is strictly greater than the third, thus 2p = a +b +c >2c and so on. So p −a, p −b, p −c are all positive. By Heron’s formula for area and the AG Inequality

7. THE GAUSS-BONNET THEOREM - University of …

7. THE GAUSS-BONNET THEOREM The Gauss-Bonnet Theorem is one of the most beautiful and one of the deepest results in the differential geometry of surfaces. It concerns a surface S with boundary S in Euclidean 3-space, and expresses a relation between: • the ...
