Dynamical systems arising from elliptic curves

P. D'Ambros, G. Everest, R. Miles, T. Ward (2000)

Colloquium Mathematicae

Similarity:

We exhibit a family of dynamical systems arising from rational points on elliptic curves in an attempt to mimic the familiar toral automorphisms. At the non-archimedean primes, a continuous map is constructed on the local elliptic curve whose topological entropy is given by the local canonical height. Also, a precise formula for the periodic points is given. There follows a discussion of how these local results may be glued together to give a map on the adelic curve. We are able to give...

The Ljunggren equation revisited

Konstantinos A. Draziotis (2007)

Colloquium Mathematicae

Similarity:

We study the Ljunggren equation Y² + 1 = 2X⁴ using the "multiplication by 2" method of Chabauty.
