| Research Abstract |
I. Mordell-Weil Lattices of Jacobian Varieties.
Basic Theory and Applications
II. Construction of Jacobian Varieties with high Mordell-Weil Rank. We have established the following :
Theorem For any integer g > 0, there exist infinite family of algebraic curves whose Jacobian varieties have Mordell-Weil rank ≧ 4g + 7.
This result greatly improves Neron's assertion (1954) of existence of curves with rank ≧ 3g + 7.
