Abstract
In this paper we establish a class of arithmetical Fourier series as a manifestation of the intermediate modular relation, which is equivalent to the functional equation of the relevant zetaβfunctions. One of the examples is the one given by Riemann as an example of a continuous nonβdifferentiable function. The novel interest lies in the relationship between important arithmetical functions and the associated Fourier series. E.g., the sawβtooth Fourier series is equivalent to the corresponding arithmetical Fourier series with the MΓΆbius function. Further, if we squeeze out the modular relation, we are led to an interesting relation between the singular value of the discontinuous integral and the modification summand of the first periodic Bernoulli polynomial.

We present a new version ''at s=1'' of Rubin's refined, higher order Stark conjecture at s=0 for an abelian extension of number fields (K. Rubin, 1996, Ann. Inst. Fourier 46, No. 1, 33-62). The key idea is to introduce a formalism of ''twisted zeta-functions'' to replace the L-functions underlying R
We show how various known results concerning the Barnes multiple zeta and gamma functions can be obtained as specializations of simple features shared by a quite extensive class of functions. The pertinent functions involve Laplace transforms, and their asymptotics is obtained by exploiting this. We
