On a Theorem of Gauss [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1935
Professor Hemraj has given a proof of a part of a theorem of Gauss without using the theory of quadratic residues. Proceeding on similar lines, I have obtained a complete proof which is rather simpler and certainly more concise.

Gauss Optics and Gauss Sum on an Optical Phenomena [PDF]

open access: yesFoundations of Physics, 2008
In the previous article (Found Phys. Lett. {\bf{16}} 325-341), we showed that a reciprocity of the Gauss sums is connected with the wave and particle complementary. In this article, we revise the previous investigation by considering a relation between the Gauss optics and the Gauss sum based upon the recent studies of the Weil representation for a ...

Block Gauss and Anti-Gauss Quadrature with Application to Networks [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2013
Approximations of matrix-valued functions of the form $W^Tf(A)W$, where $A \in {\mathbb R}^{m\times m}$ is symmetric, $W\in{\mathbb R}^{m\times k}$, with $m$ large and $ k\ll m$, has orthonormal columns, and $f$ is a function, can be computed by applying a few steps of the symmetric block Lanczos method to $A$ with initial block-vector $W\in{\mathbb R}^
