Kantorovich theorem

theorem about initial conditions that insure the convergence of Newton's method

In mathematics (especially numerical analysis), the Kantorovich theorem (or the Newton-Kantorovich theorem) is a mathematical statement about the convergence of Newton's method.[1][2][3] This theorem was named after Leonid Kantorovich,[1] and it is frequently used in the field of validated numerics.[4]
