We provide geometric algorithms for checking the stability of matrix difference equations π‘₯ 𝑛 = 𝐴 π‘₯ 𝑛 βˆ’ π‘š + 𝐡 π‘₯ 𝑛 βˆ’ π‘˜ with two delays π‘š , π‘˜ such that the matrix 𝐴 𝐡 βˆ’ 𝐡 𝐴 is nilpotent. We give examples of how our results can be applied to the study of the stability of neural networks.
