Zeros of random trigonometric polynomials with dependent coefficients
(2021-05)It is well known that the expected number of real zeros of a random cosine polynomial (of degree $ n $)\begin{equation*} V_n(x) = \sum_ {j=0} ^{n} a_j \cos (j x) , \quad x \in (0,2\pi) , \end{equation*} where the coefficients ...
