  • Homogeneous Poisson Structures on Loop Spaces of Symmetric Spaces 
    Pickrell, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    This paper is a sequel to [Caine A., Pickrell D., Int. Math. Res. Not., to appear, arXiv:0710.4484], where we studied the Hamiltonian systems which arise from the Evens-Lu construction of homogeneous Poisson structures on ...
  • Loops in SU(2), Riemann Surfaces, and Factorization, I 
    Basor, E.; Pickrell, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In previous work we showed that a loop g:S¹→SU(2) has a triangular factorization if and only if the loop g has a root subgroup factorization. In this paper we present generalizations in which the unit disk and its double, ...
  • Werner's Measure on Self-Avoiding Loops and Welding 
    Chavez, A.; Pickrell, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    Werner's conformally invariant family of measures on self-avoiding loops on Riemann surfaces is determined by a single measure μ0 on self-avoiding loops in C∖{0} which surround 0. Our first major objective is to show that ...
