Studies on complex dynamics of transcendental entire functions

The summary of research results is as follows.1. Morosawa considers dynamics of complex error functions. In particular, he studies the parameter space of those functions with real coefficients. He obtains results on parabolic bifurcations along boundaries of hyperbolic components in the parameter space.2. Complex error functions belong to the family of the structurally finite entire functions, which is defined by Taniguchi. Structurally finite entire functions with two singular values are classified into three types; complex error functions, simply decorated exponential maps and cubic polynomials. Morosawa and Taniguchi study the hyperbolic components in the parameter space of structurally finite entire functions with two singular values. They obtain results on hyperbolic component of capture type and prepare a paper.3. Taniguchi considers covering structure of rational functions and entire functions and those dynamical structure and studies those relationships. He also gives a model of asymptotic Teichimiiller space.4. Tohge improves the condition on the uniqueness theorem of meromorphic functions defined in the plane. In particular, he obtains a result on a relations of two functions which comes from conditions on angular domains.5. Kisaka constructs transcendental entire functions with doubly connected wandering domain and, more generally, those with n-multiply connected wandering domains by using improved quasiconformal surgery. He also gives a characterization on semihyperbolicity of transcendental entire functions by using orbits of singular values.8. Ishizaki studies a relation ship between properties on solutions of the Schroder equations in value distribution theory and in theory of complex dynamics.
