TY - JOUR N2 - The main objective of this work is to provide a closed formula for the backward and symmetric solution of the 2-D implicit Roesser model. The relative forward and backward fundamental matrix is of fundamental importance in our approach. An algorithm for the determination of the backward fundamental matrix sequense is also given.
