Commuting graphs have emerged as a powerful framework for elucidating complex relationships within finite group theory. In these graphs, vertices typically represent non-central elements of a ...

Several other problems about hamilton circles in infinite graphs have been proposed by Georgakopoulos: Conjecture 3 (Georgakopoulos): If G is a 4-edge-connected locally finite graph, then its line ...

Finite model theory is naturally related to complexity theory, as we may ask questions like what’s the time complexity to query a finite relational structure with a formula from some logic, and also ...

This paper focuses on finite-time partial topology identification of multi-group models, in which stochastic perturbation, multiple dispersal and time delay are included. Moreover, a novel finite-time ...

Guided by finite-time stability techniques and the graph theory, our protocol is applied for multi-system in interaction with different nonlinear models. As illustrative examples, under the proposed ...
