An Interior Point Method for Bordered Block-Diagonal Linear Programs
SIAM Journal on Optimization, 1996Summary: This paper presents an interior point method for solving a bordered block-diagonal linear program which consists of a number of disjoint blocks coupled by a total of \(p\) variables and constraints. This structure includes the well-known block-angular and dual block-angular structures, as well as their special cases, such as staircase problems,

Counting the Number of Points on Affine Diagonal Curves
2001The number of points on affine diagonal curves aX m + bY n = c over finite fields can be computed in terms of cyclotomic numbers. The approach of Berndt, Evans and Williams [1] is to express the number of points in terms of generalized Jacobi sums, then to relate the Jacobi sums Jr(χ u , χ v ) to cyclotomic numbers.

Extreme Points for Linear Optimal Control Problems with Diagonal Structure
SIAM Journal on Control and Optimization, 1992The paper gives a characterization of the extreme points of linear optimal control problem with diagonal structure. The conditions presented are shown to be equivalent to those derived by \textit{A. F. Perold} [SIAM J. Control Optimization 19, 52-63 (1981; Zbl 0488.49019)].

Multivariate approximants with branch points I. Diagonal approximants
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1978Abstract The existing scheme of rational polynomial approximants, defined from multivariate power series, is extended by defining approximants with branch points. The basic properties used to define the rational approximants can be preserved almost intact.

On Fixed Points, Diagonalization, and Self-Reference
2016We clarify the respective roles fixed points, diagonalization, and selfreference play in proofs of Godel’s first incompleteness theorem. The character of a Festschrift, I understand, allows for personal recollections of the honoree, so indulge me when I start out with a few of those . . . It must have been 1998–99—Volker Halbach had joined our ranks in

The overestimation of gaze for horizontal, vertical, and diagonal fixation points
PerceptionA widely known result from gaze-perception research is the overestimation effect where gaze endpoints are seen farther to the side than they actually are. While horizontal gaze directions have been studied repeatedly, there is scarce research on other directions after early reports that vertical gaze is perceived accurately.
