Even after Schwartz's work one of my references says
the Dirac delta function was *not* considered a respectable
function by mathematicians, but they admitted the use of a symbol
with all the same properties. Physicists persist in this "error"
with considerable profit, however.
If Dirac's delta is a function, then heat is a substance.
The generalized fns are in the dual space of L2 . I guess that makes
them functions and the statement undecided.
