Hausdorff Measure
Let 
be a Metric Space, 
be a Subset of , and 
a number 
. The -dimensional Hausdorffmeasure of , 
, is the Infimum of Positive numbers 
such that for every 
, can be coveredby a countable family of closed sets, each of diameter less than 
, such that the sum of the thPowers of their diameters is less than . Note that may be infinite, and need not be anInteger.
