Zero and Pole Distribution of Diagonal Pad
Dedicated to the memory of Douglas Sears This report is a preprint version of a paper that has been accepted for publication in a special issue of Questiones Mathematicae, to honor the South African mathematician Douglas Sears. ABSTRACT The polynomials P n and Q m having degrees n and m respectively, with P n monic, that solve the approximation problem P n (z)e ?z + Q m (z) = O ? z n+m+1 will b...
متن کاملOn the property of for a second-order system with zero diagonal coefficient
Abstract: This paper investigates the problem of whether all trajectories of the system and cross the vertical isocline, which is very important for the existence of periodic solutions and oscillation theory. Sufficient conditions are given for all trajectories to cross the vertical isocline.
متن کاملDiagonal forms and zero-sum (mod 2) bipartite Ramsey numbers
Let G be a subgraph of a complete bipartite graph Kn,n. Let N(G) be a 0-1 incidence matrix with edges of Kn,n against images of G under the automorphism group of Kn,n. A diagonal form of N(G) is found for every G, and whether the row space of N(G) over Zp contains the vector of all 1’s is determined. This re-proves Caro and Yuster’s results on zero-sum bipartite Ramsey numbers [3], and provides...
متن کاملDiagonal forms for incidence matrices and zero-sum Ramsey theory
We consider integer matrices Nt whose rows are indexed by the t-subsets of an n-set and whose columns are all distinct images of a particular column under the symmetric group Sn. Examples include matrices in the association algebras of the Johnson schemes. Three related problems are addressed. What is the Smith normal form (or a diagonal form) for Nt and the rank of Nt over a field of character...
متن کاملBlock Diagonal Gmd for Zero-padded Mimo Frequency Selective Channels with Zero-forcing Dfe
In the class of systems with linear precoder and zeroforcing (ZF) DFE for zero-padded MIMO frequency selective channels, existing optimal transceiver designs present two major drawbacks. First, the optimal system requires a large number of bits to encode the full precoding matrix. Second, the full precoding matrix leads to complex computations. These disadvantages become more severe as bandwidt...
