AR(1) sequence with random coefficients: Regenerative properties and its application

Krishna B. Athreya, Koushik Saha, Radhendushka Srivastava

Let ${X_{n}}_{n \geq 0}$ be a sequence of real valued random variables such that $X_{n} = ρ_{n} X_{n - 1} + ε_{n}, n = 1, 2, \dots$ , where ${(ρ_{n}, ε_{n})}_{n \geq 1}$ are i.i.d. and independent of initi…

Universality in the fluctuation of eigenvalues of random circulant matrices

Kartick Adhikari, Koushik Saha

We show that the linear statistics of eigenvalues of circulant matrix obey the Gaussian central limit theorem for a large class of input sequences.
