q-analogue non-homogeneous wave equations are solved by a Duhamel solution strategy using constructions with q-analogue Fourier multipliers to compensate for the dependence of the analogue ...
Non-homogeneous metric measure spaces provide a versatile framework for extending classical harmonic analysis to settings where the underlying measure does not satisfy the usual doubling property.
