I have got two definitions of t; the first I fix with the definition 'let t
: N ---> N be arbitrary'. In the second, I have t as the number of primes
in
a set J that divide n. Immediately after the first definition, I define
c(n)
as (t(n)(t(n)-1))/2. Is it OK to retain this definition - without any
statement - once I move on to my second definition?
With thanks.
