Summary: The aim of the paper is to introduce and study a new class of spaces called mildly $(1,2)^*$-normal spaces and a new class of functions called $(1,2)^*$-$\mathop{\rm rg}$-continuous, $(1,2)^*$-${\rm R}$-map, almost $(1,2)^*$-continuous function and almost $(1,2)^*$-${\rm rg}$-closed function in bitopological spaces. Subsequently, the relationships between mildly $(1,2)^*$-normal spaces and the new bitopological functions are investigated. Moreover, we obtain characterizations of mildly $(1,2)^*$-normal spaces, properties of the new bitopological functions and preservation theorems for mildly $(1,2)^*$-normal spaces in bitopological spaces. (English)
