See above. I acknowledge you explained to me why generalized functions
and distributions were introduced. I am still uncertain whether or not
the distributions would also make sense with the restriction to IR+.
Of course, I would not expect such "IR+ distribution" to provide the
derivative of Dirac delta.
To some extent I also ask for clarity how to deal with zero. It is still
my gut feeling that as far as real numbers represent real time,
exclusion of zero like a neutral position between IR+ and IR- does not
make sense. In principle, the whole issue is of no relevance for an
elapsed-time based analysis just within IR+ because in this case there
is no stationary value at zero. Imagine the function of time permanently
moving towards larger elapsed time and getting new values at its origin.
Admittelly, this notion of time is quite uncommon. I merely have to
explain how the analysis in IR+ relates to Heaviside's trick buoying
generations up with seeming symmetry.
Let me add why I do not completely trust in Abraham Robinson's
hyperreals. He reached a lot of improvement. However, he did not abandon
the relations larger equal and smaller. So he cannot release Buridan's
donkey because this would require to accept that integers and other
discrete values are of no special weight (in the sense of distributions)
within a continuum. I see any attempt to completely bridge the gap
between finite and infinite doomed to fail. Why not accepting this and
declare the donkey cheating from the very beginning? It cannot be at a
neutral position if it is expressed in terms of a continuum. A continuum
can be cut through, a number not. Do no longer believe the fairy tail
that integrals and reals are about the same matter.
