A weighted Complete Intersection conjecture for Lagrangians
A weighted Complete Intersection conjecture for Lagrangians
Let be a -intersecting -graph, meaning that any two edges of have intersection of size at least . For integers , , and , let be the -graph on whose edges have sizes between and . For a weighting , write for the corresponding weighted edge sum, and require to be a weighted -intersecting set system. Weighted Complete Intersection conjecture. Then
where the maximum is implicitly taken over all such weightings . This would extend the Complete Intersection Theorem from edge counts to Lagrangians of -intersecting -graphs; the supplied text presents it as a question toward a complete intersection theorem, and gives no resolution.
