Biography
Ostrogradski presented three important papers on the theory of heat, double integrals and potential theory to the Academy of Sciences. Largely on the strength of these papers he was elected an academician in the applied mathematics section. He made important contributions to partial differential equations, elasticity and to algebra publishing over 80 reports and giving lectures. His work on algebra was an extension of Abel's work on algebraic functions and their integrals.
