Suppose is a non-empty set, and is a distance metric; thus, is a metric space. Now suppose we have self mappings These mappings are said to fulfil CLRg property if
for some
Next, we give some examples that satisfy the CLRg property.
Examples
=Example 1 =
Suppose is a usual metric space, with Now, if the mappings are defined respectively as follows:
for all Now, if the following sequence is considered. We can see that
\lim_{k\to \infty}fx_{k} = \lim_{k\to \infty}gx_{k} = g0 = 0,
thus, the mappings and fulfilled the CLRg property.
Another example that shades more light to this CLRg property is given below
