| Research Abstract |
The Mordell-Weil group of elliptic curve itself is not only a very interessting theme of mathematical research but also a very important one in connection with number theory especially arithmetic of elliptic curves. Since H. Poincare defined the Rang of elliptic curves and proposed the problem, to what number should be attained by Rang, it have been a important theme of algebraic geometry to get the upper bound of the Rang. L.J. Mordell proved the finiteness of that number but the boundedness has not been showed tillnow. By this reason the research is carried on to seak examples of elliptic curves with possiblly large rank. Tate & Shafarevich'sresult on the case of rational function field suggests the unboundedness of the rank of elliptic curves in general, but I am sorry not to have any answer to this problem now. For the reseach in the future it seams to be very important to investigate the historical development and clearify the results of research at present.
