The book is suggested as collateral reading for people interested in "fixed point theorems for contractive type mappings". We continue the investigation of the rth-order Hardy Rogers map in the setting of cone metric spaces. Some open problems in the form of exercises are proposed. The reader comes to grasp with the nitty-gritty ideas of pure mathematical modeling in research. Construction of theorems and proof writing is developed. Researchers in fixed point theory and their students will find it a delight to read
