Abstract
This Issues Column! This issue's Open Problem Column is by P.G. Walsh and is Integral Points on Elliptic Curves: A Journey into Speculative Number Theory.
Request for Columns! I invite any reader who has knowledge of some area to contact me and arrange to write a column about open problems in that area. That area can be (1) broad or narrow or anywhere inbetween, and (2) really important or really unimportant or anywhere inbetween.

Principal Pivoting Method for Solving Column Sufficient Complementarity Problems
The linear complementarity problem (q, A) is to find, for a given real square matrix A of order n and a real column vector q of order n, a nonnegative vector z such that A z + q \geq 0$ and zt(A z + q) =0. It is known that when A is a positive ...
Scaling Matrices to Prescribed Row and Column Maxima
A nonnegative symmetric matrix $B$ has row maxima prescribed by a given vector $r$, if for each index $i$, the maximum entry in the $i$th row of $B$ equals $r_i$. This paper presents necessary and sufficient conditions so that for a given nonnegative ...
