Dec 19, 2012 at 13:51 comment added user9072 I originally left this commen on the question but in seems better here. The mentioned article also contains: "For the whole year [1954] he [Grothendieck] tried without success to make headway on the problem of approximation in topological vector spaces, a problem that was resolved only some twenty years later[...]" I am not precisely sure about the timeline, but the statement to Malgrange might be after this failure. Or, he redecided it was not quite so dead in a short time. In any case, in view of this I would even give less weight to this statement.
Mar 11, 2012 at 8:21 comment added Charles Matthews The framing of the issue matters. If TVS is taken to be a theory supporting rigorous quantum field theory, then pronouncing it dead is obviously premature. I was implicitly suggesting that the axiomatic approach, and consideration of the circle of ideas introduced by Laurent Schwartz, might reasonably explain the content of the statement. It doesn't mean, for example, that Fréchet algebras will never have a good theory.
Mar 11, 2012 at 5:30 comment added Uday Thanks for the response. It is well known that Weil never liked Grothendieck's approach. Your answer only gives a reason why we should take Grothndieck's words with a grain of salt. It does not show that TVS is not actually dead.
