A Combinatorial Formula for Recursive Operator Sequences and Applications

Raul E. Curto, Abderrazzak Ech-charyfy, Kaissar Idrissi +1

We study sequences of bounded operators \((T_n)_{n \ge 0}\) on a complex separable Hilbert space \(\mathcal{H}\) that satisfy a linear recurrence relation of the form $$ T_{n+r} =…
