A lemma stating that if a function is integrable, the magnitude of its Fourier [for-ee-ay] transform tends to zero at infinity is named for Lebesgue [l'-behg] and this man.
A lemma stating that if a function is integrable, the magnitude of its Fourier [for-ee-ay] transform tends to zero at infinity is named for Lebesgue [l'-behg] and this man. He also names a class of objects whose tangent bundles' inner products vary smoothly, his namesake manifolds. A limit of a sum of terms like f( xk*) Δ xk ["f of x sub k-star, times delta x sub k"] over subintervals defines his namesake "sums". Identify this mathematician whose namesake hypothesis on the zeta function remains unproven, and who names a rectangular approximation method for integrals.
