Query: Measures of association between algebraic varieties   This paper begins the exploration of what we call measures of association
between two irreducible complex projective varieties of the same dimension. The
idea is to study from various points of view the minimal complexity of
correspondences between them. We extend to this setting results about degrees
of irrationality for hypersurfaces, and we study joint covering invariants for
pairs of curves and hypersurfaces. We also propose a number of conjectures and
open problems.
