## Recent representation results for linear system maps: a short survey.(English)Zbl 1128.93027

Summary: We give an expression for the most general input-output map associated with the members of a certain important large family of multidimensional linear shift-invariant systems with bounded Lebesgue-measurable inputs. The expression given is an iterated function-space limit of a convolution. We also give a necessary and sufficient condition under which the limit can be written as a convolution with an integrable impulse-response function. A key role is played by a certain family of weighting operators. It is observed that for the large family of inputs and maps addressed, the Dirac impulse-response concept is in fact not the key concept concerning the representation of $$H$$, and that instead the input-output properties of $$H$$ are determined, in general, by a certain type of family of responses. Some related material concerning other results, engineering education, and discrete-space systems, is also given.
