摘要

本文提出了一个包含动态认知映射和非局部记忆整合的消费者-资源系统。该模型使用空间卷积核表示资源感知,捕获消费者与其环境之间的非局部交互。建立了二维空间周期边界条件下经典解的整体存在性,并证明了特定参数范围内齐次稳态的整体稳定性。此外,还进行了数值模拟,探讨了感知半径R对系统动力学的影响。我们的研究结果表明,感知半径在诱导从均匀状态到复杂时空模式的相变中起着关键作用,强调了认知感知尺度在生态自组织中的重要性。

Global solvability and stability of cognitive consumer-resource model with nonlocal usage of memory
In this paper, we formulate a consumer-resource system incorporating dynamic cognitive mapping and nonlocal memory integration. The model represents resource perception using a spatial convolution kernel, capturing nonlocal interactions between consumers and their environment. We establish the global existence of classical solutions under periodic boundary conditions in two spatial dimensions and demonstrate the global stability of homogeneous steady states within specific parameter regimes. Additionally, numerical simulations are conducted to explore the influence of the perception radius R on system dynamics. Our results reveal that the perception radius plays a pivotal role in inducing phase transitions from uniform states to complex spatiotemporal patterns, underscoring the significance of cognitive sensing scales in ecological self-organization.
