Gelfond has worked in number theory and the theory of 

 functions of a complex variable. He established new methods 

 of analyzing transcendence of numbers. In his works (1929 and 

 1934) Gelfond solved the problem of Euler-Hilbert, proving the 

 transcendence of logarithms of algebraic numbers with alge- 

 braic bases.
