**Ádám András**: Truth functions and the problem of their realization by two-terminal graphs (Budapest, 1967)

András Ádám TRUTH FUNCTIONS AND THE PROBLEM OF THEIR REALIZATION *^|TWO-TERMINAL GRAPHS The book gives a survey of mathematical researches dealing with truth functions (i.e. Boolean functions). This is the first attempt in literature to publish a comprehensive work in this field. The monograph comprises two parts. Part I is devoted to questions inherent in the theory of truth functions; investigations concerning prime implicants, superpositional completeness, unique decomposability by repetition-free superpositions and the number of symmetry types of truth functions. Part II deals with the connections prevalent between truth functions and graphs, more precisely with the problems of realization, putting special emphasis on the question of the repetition-free realization of truth functions by two-terminal graphs. The Appendix of the work gives the summary of the open questions and the branches still to be elaborated in the theory. AKADÉMIAI KIADÓ Publishing House of the Hungarian Academy of Sciences Budapest
