we had a similar debate here just after I signed up last year. I forget the thread but I remember I was roundly thrashed for suggesting something similar to what this guy has done.
Anyone remember the thread?
There seems to be no problem with what this person has done except that the whole idea seems trivial. The operation 0/0 has already been defined in numerous ways and unlike i, which can be manipulated in equations and has concrete effects on mathematics, this "nullity," when introduced is impossible to remove. Nullity and any operation equals nullity.
That anyway, is how it appears to me. But perhaps I am missing something. Which is why I started this thread.

is 0^0 not 1?
if 0/0=nullity, what would that mean for when you are posed with finding the limit of a sequence which involves dividing by zero?
for instance, lim(x->0) of sin(x)/x = lim(x->0)cos(x)/1=1 (by l'hopitals rule), but it also equals the nullity. or am i just confused? i don't have time to look at this properly, but i'll read the paper sometime...maybe...it sounds...interesting...
If one actually do the 0/0 division one came to on result one time and onother result another time. Therefore one nullity doesn't equal another nullity. So the nullity can't be defined as a number in any number system, invented or not yet invented.
Even if you define 0/0 as q, what happens with addition? Is q+q equals 2q? Does q*q equals q^2? What happens if you divide 1 with q? Does (1/q)*q equal q again?
And the last question - what can you use this nullity for? Is it of any mathematical value?
Or is it just a funny thing to discuss, nothing else?
