The thesis is dedicated to investigation of complex-valued random variables, that is to say c-v.r.v., which being converging serieses of discrete c-v.r.v. with probability 1. We prove the theorem about purity of distribution such c-v.r.v. We also regard random vectors, defined by systems of dividing partitions on a plane, prove purity of distributions of such random vectors, and also completely detailed this theorem (found criteria of discretness, absolutely continuity and singularity). The method of investigation of c-v.r.v. of Jessen-Wintner type with the help above mentioned random vectors is offered. The essence of this method is demonstrated in researching of c-v.r.v. with independent complex t-adic digits. Are studied metric, topologic and fractal properties of spectra mentioned c-v.r.v. and random vectors.
