A couple of Sylvester matrix equations (CSME) are required to be solved simultaneously in many applications. especially in analysing the stability of control systems. However. there are some situations in which the crisp CSME are not well equipped to deal with the uncertainty problem during the stability analysis of control systems. https://www.spidertattooz.com/Kiara-Sky-Gel-Polish-Pixie-Dust-0-5-oz-G554-p8987/
