Sprindzuk V.G. 1969, American Mathematical Society, 204 pages.
This book deals with the solution of a group of questions related both to the general theory of transcendental numbers and to the metrical theory of diophantine (and also algebraic) approximations. The fundamental problem in this field has been known in the literature since 1932 as Mahler's conjecture, since it arose in connection with the classification of numbers which' he introduced.
