Introduction Euler’s Theorem Topological Equivalence Topological Invariants Bibliography References Observe that, all the examples we have seen so far with v −e+f = 2 can be deformed into a sphere. During the deformation we stretch and bend the polyhedron at will, but never identify distinct point and never tear it.

EULER’S PHI AND EULER’S THEOREM MATH 372. FALL 2005. INSTRUCTOR: PROFESSOR AITKEN The goal of this handout is to discuss Euler’s phi function culminating in a proof of Euler’s theorem. As a corollary we have Fermat’s Little Theorem. (There were two other proofs of Fermat’s Little Theorem given in class.

Returns to Scale, Homogeneous Functions, and Euler's Theorem 161 However, production within an agricultural setting normally takes place with many more than two inputs. Each of the inputs in the production process may differ with respect to whether or not the amount that is used can be changed within a specific period.

As an example, φ(40) = 16, and (9,40) = 1. Hence, Euler’s theorem says that 916 = 1 (mod 40). Similarly, 2116 = 1 (mod 40). Example. Reduce 37103 (mod 40) to a number in the range {0,1,...39}. Euler’s theorem says that 3716 = 1 (mod 40). So 37103 = 3796 ·377 = (3716)6 ·94931877133 = 1·13 = 13 (mod 40). Example. Solve 15x = 7 (mod 32).

Euler’s Theorems Theorem (Euler Circuits) If a graph is connected and every vertex is even, then it has an Euler circuit. Otherwise, it does not have an Euler circuit. Theorem (Euler Paths) If a graph is connected and it has exactly 2 odd vertices, then it has an Euler path. If it has more than 2 odd vertices, then it does not have an Euler path.

8.10. Euler’s Theorem 277 Proof. (of Euler’s Theorem 8.10.3 for Zn) Let P WWDk1 k2 k.n/.Zn/ be the product in Zn of all the numbers in Z⇤ n. Let Q WWD.k k1/.k k2/.kk.n//.Zn/ for some k 2Z⇤ n. Factoring out k’s immediately gives Q Dk.n/P.Zn/: But Q is the same as the product of the numbers in kZ⇤ n, and kZ⇤ n DZ⇤n, so we

Euler’sTheorem Euler’s theorem generalizes Fermat’s theorem to the case where the modulus is composite. The key point of the proof of Fermat’s theorem was that if p is prime, {1,2,...,p − 1} are relatively prime to p. This suggests that in the general case, it might be useful to look at the numbers less than the modulus
