Nilpotents Leave No Trace -- A Matrix Mystery for Pandemic Times
Eric L. Grinberg
Reopening a cold case, inspector Echelon, high-ranking in the Row Operations Center, is searching for a lost linear map, known to be nilpotent. When a partially decomposed matrix i…
A Gauche perspective on row reduced echelon form and its uniqueness
Eric L. Grinberg
Using a left-to-right "sweeping" algorithm, we define the \emph{Gauche basis} for the column space of a matrix . By means of the Gauche basis we interpret the row reduced echelo…
Morley Trisectors and the Law of Sines with Reflections
Eric L. Grinberg, Mehmet Orhon
We invoke the Law of Sines to prove Morley's Trisector Theorem. Though the sinusoidal function appears, the proof is safe for the trigonometrically distanced.
The admissibility theorem for the spatial X-ray transform over the two element field
Eric L. Grinberg
We consider the Radon transform along lines in an dimensional vector space over the two element field. It is well known that this transform is injective and highly overdetermin…
A Scrapbook of Inadmissible Line Complexes For the X-ray Transform
Eric L. Grinberg, Mehmet Orhon
We consider a finite field model of the X-ray transform that integrates functions along lines in dimension 3, within the context of finite fields. The admissibility problem asks fo…
Admissible Complexes for the Projective X-Ray Transform over a Finite Field
David V. Feldman, Eric L. Grinberg
We consider the X-ray transform in a projective space over a finite field. It is well known (after E. Bolker) that this transform is injective. We formulate an analog of I.M. Gelfa…
