Springer Series Title: Mathematische Zeitschrift issue:submitted Abstract: In this paper we study questions related to the growth behavior of paravector valued functions $f= f_0+\sum_{i=1}^n e_i f_i$ that satisfy the Dirac-Hodge equation $x_n (\sum_{i=0}^n \frac{\partial }{\partial x_i} e_i)f + (n-1) f_n = 0$ on the upper half-space of $\mathbb{R}^{n+1}$. The Dirac-Hodge operator provides a linearization of the Laplace-Beltrami operator on the upper half-space. First we prove a Cauchy type estimate for solutions to the Dirac-Hodge equation. This gives us a lower bound estimate of the maximum modulus of such a solution in any ball that is contained in the upper half-space. By means of the Fourier transform we introduce lower and upper growth orders and generalizations of the maximum term and central index in the context of hypermonogenic functions on the upper half-space. In this paper we put the main focus on the study of $n$-fold periodic solutions to the Dirac-Hodge equation for which one has a discrete Fourier series representation. For every arbitrary growth order we construct non-trivial examples of $n$-fold periodic hypermonogenic functions. As main result we establish a generalization of the Valiron inequality for $n$-fold periodic solutions to the Dirac-Hodge equation on the upper half-space. This provides us with an explicit upper bound estimate of the maximum modulus $M(x_n,f)$ in terms of the maximum term and the central index associated to the Fourier series of $f$.
