Abstract :
For block structured monotone or incrementally positive n-dimensional nonlinearities, the largest class of convolution operators (multipliers) that preserve positivity is derived. These multipliers can be used in conjunction with positivity and IQC stability criteria to evaluate stability and robustness of MIMO feedback systems.
