Abstract:
We prove a general $\Omega$-theorem for the coefficients of polynomial combinations of $L$-functions from the Selberg class. As a consequence, we show that the real and imaginary parts of any linear combination of coefficients of such $L$-functions have infinitely many sign changes, provided some simple necessary conditions are satisfied.References
