Short Autobiography,lovsk. In 1952, I enrolled in the Department of Philosophy of Moscow State University. When I faced the “troubles” related to the ideologization in the humanities fields in the Soviet time, I decided to move to the Department of Mechanics and Mathematics in 1953. In 1956, I was expelled from the Uni

Dialogues and Proofs; Yankov’s Contribution to Proof Theoryn of proofs. In both cases the method is used for providing constructive proofs of important metalogical results concerning classical logic and fundamental mathematical theories. In the first paper it is shown that impredicative extensions of intuitionistic versions of arithmetic, analysis and set t

The Invariance Modalitygiven by a classical model endowed with a group of automorphisms, where a boxed formula is true iff it holds invariantly (i.e. it remains true whenever an automorphism is applied to the individuals it is talking about). With this interpretation, . modalities collapse, but . modalities remain quite i

A Note on Disjunction and Existence Properties in Predicate Extensions of Intuitionistic Logic—An Apuitively, PEI’s must resemble intuitionistic logic. We discuss PEI’s from the viewpoint of disjunction property (DP) and existence property (EP). Note that DP and EP are regarded as “hallmarks” of constructivity of intuitionistic logic. There are, however, uncountably many PEI’s having both of DP an

On V.A. Yankov’s Existential Interpretation of the Early Greek Philosophy. The Case of Heraclitusoblematic in it. Examining his broad research program in the case of Heraclitus, we show that Yankov’s contribution is that he transformed an earlier vague hypothesis about the existential problematic in the early Greek philosophy into a research problem. He challenged the interpretation of the earl
