Alexander S. Karpenko was born on 7 April, 1946, in the city of Kuibyshev (now Samara, Russia). In the same year, his parents returned to their home town of Mogilyev in Byelorussia. After graduating, in 1965, from Mogilyev polytech, he served in the army. After the army, studied philosophy at the Moscow State University as an undergraduate and then a postgraduate student specializing in logic. In 1979, he got a degree PhD and, in 1991, a degree D.Sci with the thesis Fatalism and Contingency of the Future: a Logical Analysi. Since 1977, A. S. Karpenko has been doing research at Institute for Philosophy of Russian Academy of Sciences, where he has been the head of Department of Logic since 2000. Alexander Karpenko is also a professor of the Moscow State University and a member of Russian Academy of Natural Sciences. Editor-in-chief of the annual almanach Logical Investigations published in Russian and English.
- Early publications are devoted to a new type of semantics for many-valued logics, which have been called "factor-semantics". The most important result contained in this body of work is the Boolean algebras can be used to interpret a wide class of many-valued logics, and the truth-values themselves can be understood as certain subsets of the set of Boolean-valued vectors.
- By use of the logical matrices to prove the independence of axioms were constructed the different finite Boolean lattices of implicative and implicative-negative logics. The main result of this work is a construction of a "maximal" lattice that includes most important implicative logics.
- A number of publications is devoted to a radically new outlook on the nature of prime numbers and their logical properties. As a result, prime numbers were structured in the form of rotted trees and an algorithm of building such trees out of each of the prime numbers has been developed. Also the Sheffer stroke operator for prime numbers is constructed. A combination of various algebro-logical definitions of prime numbers led to the law of generation of the classes of prime numbers.
- As the final result of the research in the field of multi-valued logics the monograph " The Development of Many-valued Logic" has been published (M., 2010) where the development of multi-valued logic is traced from Aritotle to the modern day. The special attention is paid to the results obtained by Russian logicians.
- From 2000, the scientific interests have started to take a new direction. As well as the problem of the foundations of mathematics has risen hundred years ago, now there is the problem of the foundations of logic itself. It has been shown that at the end of the XX century the question "What is logic" has become actively discussed. This question itself points at the crisis of the foundations of logic, which has led to the complete reevaluation of the status of logic and its purpose.
- Apart from purely logical, wider philosophical topics have also been developed, such as the various fatalistic arguments. The main thesis of this line work is that the phenomenon of the free will is intimately connected with a very difficult problem of the changeability of the past. Recently have been analyzed the theories which require the realization to the actuality of all the physical possibilities and in addition to that – all of which is being thought of as possible. This signifies the transition from the substantial thinking to the modal thinking. This way the philosophical paradigm emerges with the completely new range of problems, which is supported by the modern development of cosmology in the form of the various theories of the multiverse.
- In a series of works pen-named A. Belovezhski the problem of K-totalitarianism has been developed.
- Under the pen-name A. Chakha poetry and short stories are published.
