Gaussian Fluctuation for Smoothed Local Correlations in CUE

Abstract: Motivated by the Rudnick-Sarnak theorem we study limiting distribution of smoothed local correlations of the form $$ \sum_{j_1, j_2, \ldots, j_n} f(N*(\theta_{j_2}-\theta_{j_1}), N*(\theta_{j_3}-\theta_{j_1}), \ldots, N*(\theta_{j_n}-\theta_{j_1}))$$ for the Circular United Ensemble of random matrices for sufficiently smooth test functions.
