Outline of Final Research Achievements

In Nevanlinna theory of several complex variables of the second main theorem type has been of central importance. We, jointly with Winkelmann (Bochum Univ.) and Yamanoi (T.I.T.) obtained results, most advanced so far now. Jointly with Corvaja (Udine Univ.) we obtained an application and an arithmetic analogy of this result, which is of very new type and of interest; in the course we extended, certain classical result of Lang-Ax for entire holomorphic curves (originally only for 1-parameter subgroups). We, jointly with Abe (Hiroshima Univ.) and Hamano (Fukushima Univ.), solved Oka's extra zero problem which was posed by K. Oka in his posthumous paper (1945) for a generalization of Oka's principle.
In Oka-Cartan theory, which is the fundamental part of the present research, a number of improvements and simplifications were obtained. Two monographs including those results were published, and some new themes have come out.
