Multipliers are continuous linear operators which commute with translation operators. In this thesis multipliers for different Banach spaces over hypergroups are characterized and the correlations of various spaces of multipliers are studied. Furthermore, multipliers for Banach spaces over the dual object S, the support of the Plancherel measure, are investigated. Since S does in general not admit a dual hypergroup structure not all results are transferable to the dual object. However, using weak dual structures some characterizations for multipliers can also be proven in this case.
Finally, the theory of multipliers is applied to invariant linear systems in time series analysis.
