The theory of R-trees is a well-established and important area of geometric group theory and in this book the authors introduce a construction that provides a new perspective on group actions on R-trees. They construct a group RF(G), equipped with an action on an R-tree, whose e…

"Based on the authors' extensive teaching, and assuming no previous study in logic, this informal yet rigorous text covers the material of a standard undergraduate first course in mathematical logic. At each stage of the text new methods and concepts are introduced intuitively i…
Assuming no previous study in logic, this informal yet rigorous text covers the material of a standard undergraduate first course in mathematical logic, using natural deduction and leading up to the completeness theorem for first-order logic. - ;Assuming no previous study in log…
