Abstract
This paper deals with the concepts of upper and lower
\((\tau_1,\tau_2)\)-precontinuous multifunctions.
Some characterizations of upper and lower \((\tau_1,\tau_2)\)-precontinuous multifunctions are investigated. The relationships between upper and lower \((\tau_1,\tau_2)\)-precontinuous multifunctions and the other types of continuity are discussed.
