The common definition of uniform convergence is based on sequence, that is, the functions are indexed by natural numbers. But what if the functions are indexed by real number, e.g.

uniformly as

? I guess the definition might be: for any

, there is a

such that

for all

whenever

. My question is: Is it right to exclude the point

, like we do for ordinary definition of limits?

In addition, Does this type of uniform convergence preserves properties like differential, integral and limits of functions, as does the common case? Thanks!
