Edge-connectivity matrices and their spectra
Tobias Hofmann, Uwe Schwerdtfeger
The edge-connectivity matrix of a weighted graph is the matrix whose off-diagonal - entry is the weight of a minimum edge cut separating vertices and . Its computation…
Exact recursive updating of uncertainty sets
Robin Hill, Yousong Luo, Uwe Schwerdtfeger
This paper addresses the classical problem of determining the set of possible states of a linear discrete-time system subject to bounded disturbances from measurements corrupted by…
Eigenvalue bounds for the signless -Laplacian
Elizandro Max Borba, Uwe Schwerdtfeger
We consider the signless -Laplacian of a graph, a generalisation of the usual signless Laplacian (the case ). We show a Perron-Frobenius property and basic inequalites for…
Exact recursive estimation of linear systems subject to bounded disturbances
Robin Hill, Yousong Luo, Uwe Schwerdtfeger
This paper addresses the classical problem of determining the sets of possible states of a linear discrete-time system subject to bounded disturbances from measurements corrupted b…
The Distribution of Heights of Discrete Excursions
Uwe Schwerdtfeger
We compute the limiting distribution of height of a random discrete excursion with step sets consisting of one positive step 1 and arbitrary finite set of non-positive integers. Th…
Properties of sub-matrices of Sylvester matrices and triangular toeplitz matrices
Yousong Luo, Robin Hill, Uwe Schwerdtfeger
In this note we discover and prove some interesting and important relations among sub-matrices of Sylvester matrices and triangular toeplitz matrices. The main result is Hill's ide…
