Mitochondrial function is fundamental to neuroregeneration,particularly in neurons,where high energy demands are essential for repair and recovery(Patrón and Zinsmaier,2016;Beckervordersandforth et al.,2017;Iwata et al.,2023).Mitochondrial dysfunction,characterized by an imbalance in ATP levels and excessive production of mitochondrial reactive oxygen species,is a key factor that impedes neural regeneration in neurodegenerative diseases and after neuronal injury(Han et al.,2016,2020;Zheng et al.,2016;Zong et al.,2024).

The Mc Kean-Vlasov filtering problem is a special kind of filtering problem, with the state and/or observation processes governed by Mc Kean-Vlasov stochastic differential equations, which has extensive applications in various scenarios. In this paper, the authors will propose a novel numerical algorithm to solve the Mc Kean-Vlasov filtering problem based on the Hermite spectral method under the framework of Yau-Yau algorithm. As the first approach to numerically solving the Duncan-MortensenZakai equation associated with the Mc Kean-Vlasov filtering problem, the proposed algorithm can provide accurate estimations of the conditional expectation and conditional probability density of the state process with a reasonable online computational complexity. The efficiency of the proposed algorithm is verified both theoretically and numerically in this paper.

Ever since Brockett and Clark(1980), Brockett(1981) and Mitter(1980) introduced the estimation algebra method, it becomes a powerful tool to classify finite-dimensional filtering *** this paper, the authors investigate estimation algebra on state dimension n and linear rank n-1,especially the case of n = 4. Mitter conjecture is always a key question on classification of estimation algebra. A weak form of Mitter conjecture states that observation functions in finite dimensional filters are affine functions. In this paper, the authors shall focus on the weak form of Mitter conjecture. In the first part, it will be shown that partially constant structure of Ω is a sufficient condition for weak form Mitter conjecture to be true. In the second part, the authors shall prove partially constant structure of Ω for n = 4 which implies the weak form Mitter conjecture for this case.
