This research program belongs mainly to the area of arithmetic geometry, i.e., to the area which applies the methods of algebraic geometry to solve problems in number theory. A typical example here is the famous Fermat equation x^n + y^n = z^n, where n > 2. Fermat asserted in 1640 that this equation has no solution in positive integers, i.e., that the sum of two n-th powers can never be an n-th power, if n > 2. This was resolved in 1995 when Wiles, using ideas and results of Frey and Ribet in arithmetic geometry, proved that this assertion is indeed true.

本研究项目主要属于算术几何领域，即应用代数几何方法解决数论问题的领域。一个典型的例子是著名的费马方程 x^n + y^n = z^n，其中 n > 2。费马在 1640 年断言该方程无正整数解，即两个 n 次之和如果 n > 2，幂永远不可能是 n 次方。1995 年，Wiles 利用 Frey 和 Ribet 在算术几何中的思想和结果证明了这一断言确实正确，这一问题得到了解决。
