Almost contra \((I,J)\)-continuous multifunctions. (English) Zbl 1462.54015

Summary: The purpose of the present paper is to introduce, study and characterize the upper and lower almost contra \((I,J)\)-continuous multifunctions. Also, we investigate its relation with another well known class of continuous multifunctions.
