Terminal orders on arithmetic surfaces
Daniel Chan, Colin Ingalls
The local structure of terminal Brauer classes on arithmetic surfaces were classified in [CI21] generalising the classification on geometric surfaces carried out in [CI05]. Part of…
A differential analogue of the wild automorphism conjecture
Jason Bell, Colin Ingalls, Rahim Moosa +1
A differential analogue of the conjecture of Reichstein, Rogalski, and Zhang in algebraic dynamics is here established: if is a projective variety over an algebraically closed…
Sets of mutually orthogoval projective and affine planes
Charles J. Colbourn, Colin Ingalls, Jonathan Jedwab +3
A pair of planes, both projective or both affine, of the same order and on the same pointset are orthogoval if each line of one plane intersects each line of the other plane in at…
Matrix Factorizations of the discriminant of
Eleonore Faber, Colin Ingalls, Simon May +1
Consider the symmetric group acting as a reflection group on the polynomial ring , where is a field such that Char does not divide . We use…
On stacky surfaces and noncommutative surfaces
Eleonore Faber, Colin Ingalls, Shinnosuke Okawa +1
Let be an algebraically closed field of characteristic or zero. Let be a tame order of global dimension over a normal surface over $\mat…
Definite orthogonal modular forms: Computations, Excursions and Discoveries
Eran Assaf, Dan Fretwell, Colin Ingalls +3
We consider spaces of modular forms attached to definite orthogonal groups of low even rank and nontrivial level, equipped with Hecke operators defined by Kneser neighbours. After…
