Cross-composition product of reloids is a quasi-cartesian function
This conjecture is unsolved even for product of two multipliers.
An obviously equivalent reformulation of this conjecture for the special case of two multipliers:
Reloids are defined simply as filters on a Cartesian product of two sets. The reverse reloid of a reloids is defined by the formula: . Composition of reloids and is defined as the reloid whose base is
