Title: Projective Fraïssé limits of trees
Abstract: We continue study of projective Fraïssé limit developed by Irvin, Panagiotopoulos and Solecki. We modify the ideas of monotone, confluent, or retraction from continuum theory as well as several properties of continua so as to apply to topological graphs. As the topological realizations of the Fraïssé limits we obtain either some known continua, for example the dendrite \(D_3\) or the Cantor fan, or quite new, interesting ones for which we do not yet have topological characterizations.
