    • Invariant measures for the dnls equation 

      Lucà, R.Autoridad BCAM (2020-10-02)
      We describe invariant measures associated to the integrals of motion of the periodic derivative nonlinear Schr\"odinger equation (DNLS) constructed in \cite{MR3518561, Genovese2018}. The construction works for small $L^2$ ...
    • Pointwise Convergence of the Schr\"odinger Flow 

      Compaan, E.; Lucà, R.Autoridad BCAM; Staffilani, G. (2021-01)
      In this paper we address the question of the pointwise almost everywhere limit of nonlinear Schr\"odinger flows to the initial data, in both the continuous and the periodic settings. Then we show how, in some cases, certain ...
    • Quasi-invariance of low regularity Gaussian measures under the gauge map of the periodic derivative NLS 

      Genovese, G.; Lucà, R.Autoridad BCAM; Tzvetkov, N. (2022-01-01)
      The periodic DNLS gauge is an anticipative map with singular generator which revealed crucial in the study of the periodic derivative NLS. We prove quasi-invariance of the Gaussian measure on L2(T) with covariance [1+(−Δ)s]−1 ...
