In mathematics a Cauchy–Euler operator is a differential operator of the form ${\displaystyle p(x)\cdot {d \over dx}}$^[1] for a polynomial p. It is named after Augustin-Louis Cauchy and Leonhard Euler. The simplest example is that in which p(x) = x, which has eigenvalues n = 0, 1, 2, 3, ... and corresponding eigenfunctions xⁿ.
