Multiple academic studies confirm that there are ongoing efforts and established frameworks dedicated to the formal mathematical and computational presentation of Maturana's concept of autopoiesis.
The claim states that there are formal presentations of Maturana's concept of autopoiesis. Papers [4] and [9] explicitly discuss, develop, and analyze formalisms, mathematical models, and functional closure equations for autopoiesis. Therefore, the claim is well supported by the provided literature.
