Document Abstract
Information Technology plays a vital role in every step of human activity in
the 21st
century. In this era, we can’t imagine our life without technology
because the virtual communication takes place over traditional
communication by using various ways like video conferencing, telephoning,
Emailing, Image processing, etc. On the other hand fixed point theory is a
very traditional topic of pure part of Mathematics which plays a vital role in
many disciplinary of Mathematics such as Topology, Physics, Chemistry,
Biology, Computer Science, etc. In the second half years of the 20th
century,
researchers tried to provide a digital version of this theory. A digital image is
the form of pixels and we can consider the distance between pixels by a
distance function. As the distance between pixels is very least then we find
a good image quality while the distance is maximum then we obtain a poor
quality image. In this paper, we established existence of some new fixed
point results by taking two self-mappings for expansive mappings in digital
metric space.
