But Hormander, though it took me ages to puzzle through his writing, actually did prove the tube theorem. There were no mistakes in Hormander's book as far as I read it. Being right, not using up your time with long proofs that have mistakes in them, makes up for a great deal of obscurity.

Hormander’s Theorem Let L denote the operator L = 1 2 Xk i=1 X2 i + Y where X1,·,,Xk,Y are C∞ vector ﬁelds in Rn. Assume that the Lie Algebra generated by X1,·,,Xk,Y span Rn at every x. Then, if u is a distribution such that Lu = f and f is C∞ in an open set G, it is always true that u is C∞ in G. Proof is in three steps. Step 1.

This book presents, for the first time, the unpublished manuscripts of Lars Hormander, written between 1951 and 2007. Hormander himself organised the manuscripts and also wrote the notes explaining their origins, presenting the material in the for Olof Hörmander.

A SHARP VERSION OF THE HORMANDER MULTIPLIER THEOREM LOUKAS GRAFAKOS AND LENKA SLAV IKOVA Abstract. We provide an improvement of the H ormander multiplier theorem in which the Sobolev space Lr s (Rn) with integrability index r and smoothness index s > n=r is re-placed by the Sobolev space with smoothness s built upon the Lorentz space Ln=s;1(Rn).
