A merry-go-round with the circle map, primes and pseudoprimes
M. Leo, R. A. Leo, G. Soliani
We show that the use of the main characteristics of the circle map leads naturally to establish a few statements on primes and pseudoprimes. In this way a Fermat's theorem on prime…

Non-local Symmetries of Nonlinear Field Equations: an Algebraic Approach
M. Leo, R. A. Leo, G. Soliani +1
An algebraic method is devised to look for non-local symmetries of the pseudopotential type of nonlinear field equations. The method is based on the use of an infinite-dimensional…
