genetic nets
0.1 Introduction
Genetic ‘nets’, or networks, GN – that represent a living organism’s genome –are mathematical models of functional genes linked through their non-linear, dynamic interactions.
A simple genetic (or gene) network GNs may be thus represented by a directed graph GD whose nodes (or vertices) are the genes gi of a cell or a multicellular organism and whose edges (arcs) are arrows representing the actions of a gene aig on a linked gene or genes; such a directed graph representing a gene network has a canonically associated biogroupoid 𝒢B which is generated or directly computed from the directed graph GD.
0.2 Boolean vs. N-state models of genetic networks in LMn- logic algebras
The simplest, Boolean, or two-state models of genomes represented by such directed graphs of gene networks form a proper subcategory of the category
of n-state genetic networks, 𝐆𝐍ŁMn that operate on the basis of a Łukasiewicz-Moisil n-valued logic algebra
LMn. Then, the category of genetic networks,
𝐆𝐍ŁMn was shown in ref. [2] to form a subcategory of the
algebraic category
of Łukasiewicz algebras (http://planetmath.org/AlgebraicCategoryOfLMnLogicAlgebras), ℒℳ [1, 2]. There are several published, extensive computer simulations of Boolean two-state models of both genetic and neuronal networks (for a recent summary of such computations see, for example, ref. [2]. Most, but not all, such mathematical models are Bayesian, and therefore involve computations for random networks that may have limited biological relevance as the topology of genomes, defined as their connectivity, is far from being random.
The category of automata (or sequential machines based on Chrysippean or Boolean logic) and the category of (M,R)-systems (which can be realized as concrete metabolic-repair biosystems of enzymes, genes, and so on) are subcategories of the category of gene nets 𝐆𝐍ŁMn. The latter corresponds to organismic sets of zero-th order S0 in the simpler, Rashevsky’s theory of organismic sets.
