• Adaptive regulation in unstable MIMO LTI plants with distinct input delays2025 · аннотациясвернуть

  The paper is devoted to the problem of adaptive regulation in linear time-invariant (LTI) multi-input multi-output (MIMO) possibly unstable plants with multiple distinct input delays. The external disturbances affecting…

  Let G be a graph with adjacency matrix A(G), and let D(G) be the diagonal matrix of the degrees of G: The signless Laplacian Q(G) of G is defined as Q(G):= A(G) +D(G). Cvetkovic called the study of the adjacency matrix…

• Some Inequalities for the Largest Eigenvalue of a Graph2002 · аннотациясвернуть

  Let λ(G) be the largest eigenvalue of the adjacency matrix of a graph G: We show that if G is Kp+1-free then This inequality was first conjectured by Edwards and Elphick in 1983 and supersedes a series of previous…
