towards a shrinking target property for primitive square-tiled surfaces
abstract:
in this talk, i will discuss ongoing work to develop a method for proving a shrinking target property on primitive square-tiled surfaces that comes from the action of a subgroup $g$ of its veech group. our main tool is the construction of a fourier-like transform which we can use to relate the $l^2$-norm of the koopman operator induced by $g$ to the $l^2$-norm of a markov operator related to a random walk on $g$.
