Periods and symmetric square periods of modular forms
Let \(S_k\) denote the space of cusp forms of weight k and level one. We show that if \(k\gg n^2\) then the first n odd or even periods are linearly independent on \(S_k\). We also obtain a similar result for the symmetric square periods of modular forms.
