[HTML][HTML] Rational functions with identical measure of maximal entropy

H Ye - Advances in Mathematics, 2015 - Elsevier
We discuss when two rational functions f and g can have the same measure of maximal
entropy. The polynomial case was completed by Beardon, Levin, Baker–Eremenko, Schmidt …

Y Okuyama - arXiv preprint arXiv:2401.02005, 2024 - arxiv.org
We give a geometric description of the parabolic bifurcation locus in the space
$\operatorname {Rat} _d $ of all rational functions on $\mathbb {P}^ 1$ of degree $ d> 1 …

Approximation of non-archimedean Lyapunov exponents and applications over global fields

T Gauthier, Y Okuyama, G Vigny - Transactions of the American …, 2020 - ams.org
Let $ K $ be an algebraically closed field of characteristic 0 that is complete with respect to a
non-trivial and non-archimedean absolute value. We establish an approximation of the …

[PDF][PDF] Repelling periodic points and logarithmic equidistribution in non-archimedean dynamics

Y Okuyama - Acta Arith, 2012 - yusuke.cajpn.org
It is an open problem whether repelling periodic points are dense in the classical Julia set of
a non-archimedean rational function of degree more than one. We give a partial positive …

Quantitative approximations of the Lyapunov exponent of a rational function over valued fields

Y Okuyama - Mathematische Zeitschrift, 2015 - Springer
We establish a quantitative approximation formula of the Lyapunov exponent of a rational
function of degree more than one over an algebraically closed field of characteristic 0 0 that …

Fekete configuration, quantitative equidistribution and wandering critical orbits in non-archimedean dynamics

Y Okuyama - Mathematische Zeitschrift, 2013 - Springer
Let f be a rational function of degree d> 1 on the projective line over a possibly non-
archimedean algebraically closed field. A well-known process initiated by Brolin considers …

Effective divisors on the projective line having small diagonals and small heights and their application to adelic dynamics

Y Okuyama - Pacific Journal of Mathematics, 2015 - msp.org
We establish a quantitative adelic equidistribution theorem for a sequence of effective
divisors on the projective line over the separable closure of a product formula field having …

On a characterization of polynomials among rational functions in non-archimedean dynamics

Y Okuyama, M Stawiska - Arnold Mathematical Journal, 2020 - Springer
We study a question on characterizing polynomials among rational functions of degree> 1>
1 on the projective line over an algebraically closed field that is complete with respect to a …

Limit functions of discrete dynamical systems

HP Beise, T Meyrath, J Müller - Conformal Geometry and Dynamics of the …, 2014 - ams.org
In the theory of dynamical systems, the notion of $\omega $-limit sets of points is classical. In
this paper, the existence of limit functions on subsets of the underlying space is treated. It is …
