by ratner's famous equidistribution theorem, we know that unipotent orbits in finite volume quotients of lie groups equidistribute in their closures. often, in applications, one needs to know more: specifically, at what rate does the orbit equidistribute? we call a statement that includes a quantitative error term effective. in this talk, i will present an effective equidistribution theorem, with polynomial rate, for horospherical orbits in the frame bundle of certain infinite volume hyperbolic manifolds. this is joint work with nattalie tamam.
