Bounds for the Second Largest Eigenvalue of Real 3 × 3 Symmetric Matrices with Entries Symmetric about the Origin

Barini, Geoffrey; Kivunge, Benard; Akanga, Jotham (2012)

Let ASn[a,b] denote a set of all real nxn symmetric matrices with entries in the interval [a,b]. In this article, we present bounds for the second largest eigenvalue λ2(A) of a real symmetric matrix A, such that A∈AS3 [-b,b].
THE M_0 – MATRIX COMPLETION PROBLEM FOR DIGRAPHS OF 5×5 MATRICES WITH LESS THAN FOUR DIRECTED LINES

Njoroge, James Mwangi; Kivunge, Benard; Muondwe, Samuel Kanyi; Kinyanjui, Anthony Muthondu (2013)

A real matrix is said to be – matrix if its principal minors are non - negative and all its non - diagonal entries are non - positive. In this project, we consider the – matrix completion ...
