One Matrix to Rule Them All
Schur self-Konvolution expansion Koefficients; inversion of Laurent and power series; and associahedra, noncrossing, and reciprocal partition polynomials Springboarding off the work of Lagrange, in the 1940s Schur introduced what I will refer to (mnemonically) as the Schur self-Konvolution expansion Koefficients … Continue reading →
