Numerical evaluation of differential and semi-differential invariants
Abstract: "Soon after the appearance of Weiss's influential paper [7], I undertook a straightforward implementation of differential projective invariants. I made some experiments as a feasibility study to see qualitatively how well it seemed differential invariants could be matched. The ex...
