To its algorithms include the Pollard 's Rho- method Pollard p- 1 method and the original version of the particular Zahlkörpersiebs, which was then further developed by others.

It also resulted in 1971, the discrete Fourier transform over a finite field, a, taking into account the rapid Cooley -Tukey algorithm 1965.
