In this manuscript, we investigate the behaviour of additive mappings which satisfy a functional identity associated with generalized (α, β)-higher derivations on Lie ideals of a prime ring with involution. As the consequences of our main theorem, many well known results can be d...

The gene regulatory network (GRN) is essential to life, as it governs all levels of gene products that enable cell survival and numerous cellular functions. Wagner's GRN model, which has mathematical roots origin from the Ising model and neural networks, is a powerful computation...
