In the context of transition analysis, linear input-output analysis determines worst-case disturbances to a laminar base flow based on generic right-hand-side volumetric/boundary forcing term. The is not physically realizable, and, our knowledge, framework for posing physically-realizable disturbance problems lacking. natural receptivity are forced by matching (typically local) solutions within...

We give a complete characterization of receptive field codes realizable by connected receptive fields and their minimal embedding dimensions. In particular, we show that all connected codes are realizable in dimension at most three. To our knowledge, this is the first family of receptive field codes for which the exact characterization and minimal embedding dimension is known.
