Shigefumi Mori, 39, of Kyoto University, has devoted much of his career to pioneering methods of classifying certain kinds of surfaces defined by algebraic equations, thereby extending the classical theory of

algebraic surfaces to three dimensions.

Using this result, new methods for blending several

algebraic surfaces simultaneously are derived.

Moreover, all known values of Seshadri constants on

algebraic surfaces are rational.

As applications, we give some results supplementary to the theory of

algebraic surfaces in arbitrary characteristic.
