discrete metric space

x= any set

d(x,y)= 0, if x=y

d(x,y)=1 , if x not equals y

for any discrete space [if !msEquation] [endif] the specific nature of sample points isirrelevant as far as[if !msEquation][endif] is concerned. And we considerΩwith family integersof Z as below:       

Concrete: material used for building, cement mixed with water and etc.

Integer: the whole number such as 1, 7 instead of numbers with fractions and decimals
