LeanPool.RegtsSevenster.RS.Novel.Coordinates.CapSplit

The split cap on merged vectors #

The multiplicative midpoint of the cap recursion: the split cap (smaller cap tensored with one evaluation) evaluated on a transported merge of model vectors is the product of the smaller cap value and the strand evaluation.

The split cap is multiplicative over the merge.
