Title: Formalization of Multiway-Join Algorithms
Thibault Dardinier

Worst-case optimal multiway-join algorithms are recent seminal achievement of
the database community. These algorithms compute the natural join of multiple
relational databases and improve in the worst case over traditional query plan
optimizations of nested binary joins. In 2014, Ngo, Ré, and Rudra gave a unified
presentation of different multi-way join algorithms. We formalized and proved
correct their "Generic Join" algorithm and extended it to support negative joins.
