French mathematician. Born in Saint-Omer. Professor at the École Polytechnique from 1831, and at the Collège de France from 1851 to 1879. Member of the Academie des Sciences since 1839. In function theory, he showed that "any function that is bounded and regular on the entire complex plane is a constant," and "any elliptic function that has no poles within a periodic parallelogram is a constant." He also proved the differential equation y (n) + p 1 (x)y (n-1) + ... + p n (x)y = 0 [Kousaku Yoshida] [Reference] | | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
