TY - JOUR A1 - Orejas, Fernando A1 - Pino, Elvira A1 - Navarro, Marisa A1 - Lambers, Leen T1 - Institutions for navigational logics for graphical structures JF - Theoretical computer science N2 - We show that a Navigational Logic, i.e., a logic to express properties about graphs and about paths in graphs is a semi-exact institution. In this way, we can use a number of operations to structure and modularize our specifications. Moreover, using the properties of our institution, we also show how to structure single formulas, which in our formalism could be quite complex.
