Upper bounds for the derivative of exponential sums Academic Article uri icon

abstract

  • The equality sup is shown, where the supremum is taken for all exponential sums p of the form are also proved for all exponential sums of the above form with arbitrary real exponents. These results improve inequalities of Lorentz and Schmidt and partially answer a question of Lorentz. © 1995 American Mathematical Society.
