<p>Fix a complex number s and a real number x, does there exist an analytic continuation of the Dirichlet series </p> <p>$L(s,x):=\sum_{k=1}^{\infty}\frac{\sin^2(2\pi k x)}{k^s}$</p> <p>to the whole complex plane except 1?</p> <p>If yes, is there some functional equation verified which makes it possible to calculate $L(0,x)$?</p> <p>If yes, what about the modulus of continuity of $x\mapsto L(0,x)$? ($L(\frac{3}{2},x)$ seems to be a nice case.)</p> <p>Thanks for any comments Chri</p>
