Interest in simulation of large-scale metabolic networks, species development, and genesis of various diseases requires new simulation techniques to accommodate the high complexity of realistic biological networks. Information geometry and topological formalisms are proposed to analyze information processes. We analyze the complexity of large-scale biological networks as well as transition of the system functionality due to modification in the system architecture, system environment, and system components. The dynamic core model is developed. The term dynamic core is used to define a set of causally related network functions. Delocalization of dynamic core model provides a mathematical formalism to analyze migration of specific functions in biosystems which undergo structure transition induced by the environment. The term delocalization is used to describe these processes of migration. We constructed a holographic model with self-poetic dynamic cores which preserves functional properties under those transitions. Topological constraints such as Ricci flow and Pfaff dimension were found for statistical manifolds which represent biological networks. These constraints can provide insight on processes of degeneration and recovery which take place in large-scale networks. We would like to suggest that therapies which are able to effectively implement estimated constraints, will successfully adjust biological systems and recover altered functionality. Also, we mathematically formulate the hypothesis that there is a direct consistency between biological and chemical evolution. Any set of causal relations within a biological network has its dual reimplementation in the chemistry of the system environment.
对大规模代谢网络、物种发育以及各种疾病起源的模拟研究需要新的模拟技术来适应现实生物网络的高度复杂性。信息几何和拓扑形式主义被提出来分析信息过程。我们分析了大规模生物网络的复杂性以及由于系统架构、系统环境和系统组件的改变而导致的系统功能转变。动态核心模型得以发展。术语“动态核心”用于定义一组因果相关的网络功能。动态核心模型的非定域化提供了一种数学形式主义,用于分析在环境诱导结构转变的生物系统中特定功能的迁移。术语“非定域化”用于描述这些迁移过程。我们构建了一个具有自诗意动态核心的全息模型,该模型在这些转变下保留功能特性。对于表示生物网络的统计流形,发现了诸如里奇流和普法夫维数等拓扑约束。这些约束能够为大规模网络中发生的退化和恢复过程提供见解。我们建议,能够有效实施估计约束的疗法将成功调节生物系统并恢复改变的功能。此外,我们从数学上提出假设,即生物进化和化学进化之间存在直接的一致性。生物网络内的任何一组因果关系在系统环境的化学过程中都有其对偶的重新实现。
