Summary: An interpolant for a mutually inconsistent pair of formulas $$(A,B)$$ is a formula that is (1) implied by $$A$$, (2) inconsistent with $$B$$, and (3) expressed over the common variables of $$A$$ and $$B$$. An interpolant can be efficiently derived from a refutation of $$A \land B$$, for certain theories and proof systems. In this tutorial we will cover methods of generating interpolants, and applications of interpolants, including invariant generation and abstraction refinement.
