On A Bitopological (1,2)*- Proper Functions

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
   In this paper, we introduce a new type of functions in bitopological spaces, namely, (1,2)*-proper functions. Also, we study the basic properties and characterizations of these functions . One of the most important of equivalent definitions to the (1,
