Summary: Two projected gradient algorithms for linear programming are discussed. The first uses a conventional enough steepest edge approach, and implements a version of Wolfe's method for resolving any problems of degeneracy. The second makes use of a steepest descent direction which is calculated by solving a linear least squares problem subject to ...

Dealing with degeneracy in triangulation
Computing in Science & Engineering, 2002Here is a method for dealing with a type of degeneracy that often arises in triangulation then the input contains much regularity, such as four or more points that lie on the same circle in 2D computations or five or more on the same sphere in 3D. The paper shows a dramatic application of Francis Sullivan's and my degeneracy method by Alexander Agathos

On a Degeneracy Theorem of Kramers
American Journal of Physics, 1952There is a theorem due to Kramers which states that the energy states of systems with an odd number of electrons remain at least doubly degenerate in the presence of any purely electric fields. The physical significance of this theorem, its proof, and a discussion of the relationship of the Kramers degeneracy and the Wigner time-reversal operation are ...

Physical Review, 1962
Modern cosmological theories imply that the universe is filled with a shallow degenerate Fermi sea of neutrinos. In the steady state and oscillating models (and perhaps also the "big bang" theories) it can be shown rigorously that the proportion of filled neutrino levels (plus the proportion of filled antineutrino levels) is precisely one up to a ...
