    A new proof of the growth rate of the solvable Baumslag–Solitar groups

    We exhibit a regular language of geodesics for a large set of elements of BS(1, n) and show that the growth rate of this language is the growth rate of the group. This provides a straightforward calculation of th...

    Tame combing and almost convexity conditions

    We give the first examples of groups which admit a tame combing with linear radial tameness function with respect to any choice of finite presentation, but which are not minimally almost convex on a standard g...

    The Dehn Function of PSL2(Z[1/p])

    We show that PSL2(Z[1/p]) admits a combing with bounded asynchronous width, and use this combing to show that PSL2(Z[1/p]) has an exponential Dehn function. As a corollary, PSL2(Z[1/p]) has solvable word problem ...
