Various methods exist for the numerical solution of partial differential equations, which mostly lead to high dimensional and computationally demanding problems. These computational requirements are even higher, if the discretized problems need to be solved repeatedly, e.g. under parameter variation in the differential equations. This is relevant in cases of parameter studies, parameter identification, design or optimization. Reduced basis methods allow the efficient treatment of such parametric problems. Based on special solutions for selected parameters, the so called snapshots, low dimensional approximation spaces are constructed, which are denoted reduced basis spaces. Galerkin projection leads to a reduced computational model, which allows parameter variation and can be rapidly solved. The model error can be quantified by corresponding a-posteriori error analysis. This lecture gives an introduction in this class of model reduction techniques.
