      5 [computational_complexity] bounds on [automaton_emptiness] of intersection of constant number of [DFAs] (especially on [intersection_nonemptiness]): [oliveira2018intersection] and [oliveira2020fine]
      6 - connections to [3SUM] and [triangle_detection]
      7 - also [ascone2025are] on [regular_expressions] (for [intersection_nonemptiness])
