Transformation and summation formulae for Kampé de Fériet series

Euler's two transformations are employed to establish several general transformation formulae for double hypergeometric series. These transformations yield further a number of reduction formulae for Kampé de Fériet series of types F1:0;μ1:1;λ, F1:0;μ0:2;λ and F1:0;μ2:0;λ. By specializing certain parameters, a list of new summation formulae for these Kampé de Fériet series are obtained.
