A closed formula for linear recurrences with constant coefficients

Glenn Bruda, Bruce Fang, Pico Gilman +6

Given a linear recurrence of the form $c_{n} = a_{1} c_{n - 1} + \dots + a_{j} c_{n - j}$ , it is well-known that $c_{n} = \sum_{r} p_{r} (n) r^{n}$ , where the sum is taken over the set of characteristic root…

The Limiting Spectral Distribution of Various Matrix Ensembles Under the Anticommutator Operation

Glenn Bruda, Bruce Fang, Raul Marquez +6

Inspired by the quantization of classical quantities and Rankin Selberg convolution, we study the anticommutator operation ${\cdot, \cdot}$ , where ${A, B} = A B + B A$ , applied to…
