Assume that there exists a constant $ M> 0$ such that $/hat{u}/ >M$ .



Is the following inequality true?



$left | hat{u}right |_{L^{p}} $ $leq $ $left | hat{u}right |_{L^{2}} $
with $ 0<p<1$ .



Thanks.

  • Hello and welcome to math.stackexchange. Please give more details: $L^p$ over what set? Is $hat u$ the Fourier transform? What have you done so far? Where does this problem come from?
