The title of my research is "Riemann-Hilbert problem"(No.09640229). I studied this problem from Heisei 9th to 11th. I made 16 manuscripts in this period, 9 manuscripts already pubrished and remaining 7 manuscripts are printing. I studied this problem the following steps :(1) Making new spectral mapping theorems for p-hyponormal operators.(2) Making new general polar symbols for p-hyponormal operators.(3) Making new singular integral model for p-hyponormal operators.(4) Extending Putnam inequality to n-tuples.(5) Extending p-hyponormal operators to Riemann-Hilbert problemSteps (1) - (3) are for the research of (4) and (5). I got almost final results of these steps. Hence I finished (5) in this research period. About (4), I got some information. I made two manuscripts of this problem. Professor Tadasi Huruya is very important. I got his help. Also, I asked to come to Japan to Professor W.Zelazko, he is a professor of the Banach Institute, in Heisei 10th. And in Heisei 11th I asked to come to Japan to Professor R.Curto, he is a professor of the University of Iowa. We discussed the problem (4) and got two munscripts.
