"Attempts to unite the fields of mathematical logic and general algebra. Presents a collection of refereed papers inspired by the International Conference on Logic and Algebra held in Siena, Italy, in honor of the late Italian mathematician Roberto Magari, a leading force in the blossoming of research in mathematical logic in Italy since the 1960s."
"Many papers in this volume are valuable contributions to mathematical logic, universal algebra, and category theory, and the volume is recommended to researchers in these fields. "
