Neutrosophy. An element x(T, I, F) belongs to the set in
the following way: it is t true in the set, i indeterminate in
the set, and f false, where t, i, and f are real numbers taken
from the sets T, I, and F with no restriction on T, I, F, nor
on their sum n=t+i+f.
The neutrosophic set generalises:
theories (for 0#@n#@100 and i=0, 0#@=t,i,f#@=100);
- the
fuzzy set (for n=100 and i=0, and 0#@=t,i,f
=100);- the classical set (for n=100 and i=0, with t,f either 0 or
100);
t,f#@100);
some disjoint sets is not empty (for t=f=100 and i=0; some
paradoxist sets can be denoted this way).
