E-symmetric numbers

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.

Symmetric and Asymmetric Gaps in Some Fields of Formal Power Series

Galanova, N. (2004)

Serdica Mathematical Journal

Similarity:

2000 Mathematics Subject Classification: 03E04, 12J15, 12J25. We consider a construction of fields with symmetric gaps that are not semi-η1. By this construction we give examples of fields with different asymmetric gaps.
