DOI: 10.1007/s00009-020-01620-5
Abstract: Partial inverse problems for Dirac operators on star graphs are studied. We consider Dirac operators on the graphs, and prove that the potential on one edge is uniquely determined by part of its spectra and… read more here.

DOI: 10.1007/s00025-020-1165-x
Abstract: In this paper, Sturm-Liouville operators with frozen argument on star graphs are studied. First, we derive the asymptotic expression for the large eigenvalues. Second, the regularized trace formulae for these operators are calculated with the… read more here.

DOI: 10.1103/physreve.102.062211
Abstract: Some convergence proofs for systems of oscillators with inhibitory pulse coupling assume that all initial phases reside in one half of their domain. A violation of this assumption can trigger deadlocks that prevent synchronization. We… read more here.

DOI: 10.1103/x5kw-7svx
Abstract: Remote synchronization (RS) has recently attracted a lot of attention, but it is mainly focused on the synchronization among leaf nodes of a star graph and thus cannot be applied to the synchronization between distant… read more here.

DOI: 10.2298/aadm241101024a
Abstract: The edge versions of restricted detour polynomials were recently introduced for computing the edge versions of restricted detour indices. The generating function, which we called the edge versions of restricted detour polynomial, whose derivative is… read more here.

DOI: 10.3390/sym11020185
Abstract: We consider stationary waves on nonlinear quantum star graphs, i.e., solutions to the stationary (cubic) nonlinear Schrödinger equation on a metric star graph with Kirchhoff matching conditions at the centre. We prove the existence of… read more here.
