Pyramidal composition rules for Wronskians upon Wronskians
Robert C. Brunet · Journal of Mathematical Physics · 1975
We give composition rules for Wronskians which have Wronskians as arguments. These pyramids of Wronskians are shown to reduce to products of Wronskians of different order. Many symmetric and antisymmetric regroupings of functions are then possible. The arithmetic of Wronskians can efficiently be reduced to the application of the ℏ⇊ of the LSZ formalism.
