Computations and lower bounds for scl and the relative Gromov seminorm
… seminorm in surface groups. We explain how bounded cohomology provides a dual to the relative Gromov seminorm, and apply those ideas to obtain new computations of scl. Another aspect of this thesis is to obtain lower bounds for stable commutator length in the presence of negative curvature. …
