On the dynamical spectrum of projective K3 surfaces Brandhorst, Simon
Description
The entropy of an automorphism of a surface is the logarithm of a Salem number, that is, an algebraic integer $\lambda>1$ which is conjugate to $1/\lambda$ and all whose other conjugates lie on the unit circle. In this talk I report on work in progress on the question when some multiple $n \log \lambda$, $n \in \mathbb{N}$, arises from an automorphism of a projective K3 surface.

The entropy of an automorphism of a surface is the logarithm of a Salem
number, that is,
an algebraic integer $\lambda>1$ which is conjugate to $1/\lambda$ and
all whose other conjugates lie on the unit circle. In this talk I report
on work in progress on the question when some multiple $n \log \lambda$,
$n \in \mathbb{N}$, arises from an automorphism of a projective K3
surface.
