Some fibrational properties of normal monomorphisms

Description:  Several classes of monomorphisms have been introduced in general algebraic contexts. For some of them, there is a purely categorical description that makes it possible a formal study of their structure. In my talk, after a quick recap of such notions, I will focus on the normal subobjects in the sense of Dominique Bourn, and I will describe some (bi)fibrational properties they have. Finally, I will explore the possibility of extending the fibrational point of view to the other classes of monos mentioned above.
