E-symmetric numbers

Gang Yu (2005)

Colloquium Mathematicae

Similarity:

A positive integer n is called E-symmetric if there exists a positive integer m such that |m-n| = (ϕ(m),ϕ(n)), and n is called E-asymmetric if it is not E-symmetric. We show that there are infinitely many E-symmetric and E-asymmetric primes.

Enclosing solutions of second order equations

Gerd Herzog, Roland Lemmert (2005)

Annales Polonici Mathematici

Similarity:

We apply Max Müller's Theorem to second order equations u'' = f(t,u,u') to obtain solutions between given functions v,w.

On the nodal set of the second eigenfunction of the laplacian in symmetric domains in R N

Lucio Damascelli (2000)

Similarity:

We present a simple proof of the fact that if Ω is a bounded domain in R N , N 2 , which is convex and symmetric with respect to k orthogonal directions, 1 k N , then the nodal sets of the eigenfunctions of the laplacian corresponding to the eigenvalues λ 2 , , λ k + 1 must intersect the boundary. This result was proved by Payne in the case N = 2 for the second eigenfunction, and by other authors in the case of convex domains in the plane, again for the second eigenfunction.
