Proof Complexity of CSP
Gaysin, Azza ; Krajíček, Jan (advisor) ; Kolokolova, Antonina (referee) ; Kompatscher, Michael (referee)
In this thesis we formalize Zhuk's decision algorithm solving in p-time tractable con- straint satisfaction problems (CSPs) in a weak theory of bounded arithmetic W1 1 . As a consequence, we show that tautologies that express the negative instances of such CSPs have polynomial proofs in the quantified propositional calculus G. 1

Weighted clones Azza Gaysin January 3, 2018 Abstract In this thesis we fully describe the structure of all binary parts of weighted clones over the Boolean clones generated by one of the semilattice operations and one or two of the constant operations. We also give a complete description of all atomic and maximal weighted clones over these clones. Keywords: Relational clones, VCSP, Weighted clones 1
