Let f be an analytic function defined on a complex domain and A โ M n (C). We assume that there exists a unique ฮฑ satisfying f (ฮฑ) = 0. When f (ฮฑ) = 0 and A is non-derogatory, we completely solve the equation XA -AX = f (X). This generalizes Burde's results. When f (ฮฑ) / = 0, we give a method to sol
