TITLE: Cuts, Calculi, Complexity

ABSTRACT: I will introduce some of the research themes underlying my work: cut-elimination, developing analytic proof calculi for non-classical logics, and using such calculi to obtain decidability and complexity for substructural logics. I will provide a high-level overview and present specific topics of particular interest to me including cut-elimination for provability logics, what to do when cut-elimination fails for your favourite logic in the sequent calculus (the conventional approach), a programme rethinking this approach (and a new paradigm called cut-reduction that extends cut-elimination), and decidability and complexity for many extensions of the commutative Full Lambek calculus with weakening/contraction.
