Abstract :
We show that approximation of an element in L^p space by finite number of terms is arbitrary slow, but if we use L^q norm, with q p, as a measure of the error, then the approximation is faster. Also, we use nonlinear approximation to characterize Lorentz spaces by the error of approximation of their elements.
