Katsura introduced the notion of regular factor maps between topological graphs, which contravariantly induce a morphism between the corresponding Cuntz-Pimsner algebras. Using Katsura's result of the classification of gauge-invariant ideals by admissible pairs, I will discuss the construction of a pullback of topological graph algebras from a union of row-finite topological graphs. Joint work with John Quigg, and Mariusz Tobolski.
