Absolute Projectivities in Pascal's Multimysticum
Jaydeep Chipalkatti, Alex Ryba
The Pascal Multimysticum is a system of points and lines constructed with a straight edge starting from six points on a conic. We show that the system contains 150 infinite ranges…
Saturated Domino Coverings
Andrew Buchanan, Tanya Khovanova, Alex Ryba
A domino covering of a board is saturated if no domino is redundant. We introduce the concept of a fragment tiling and show that a minimal fragment tiling always corresponds to a m…
Rank one lattice type vertex operator algebras and their automorphism groups, II: E-series
Chongying Dong, Robert L. Griess, Alex Ryba
Let L be the A_1 root lattice and G a finite subgroup of Aut(V_L), where is the associated lattice VOA (in this case, Aut(V) is isomorphic to PSL(2,\Bbb C)). The fixed point…
Rank one lattice type vertex operator algebras and their automorphism groups
Chongying Dong, Robert L. Griess
Let L be a positive definite even lattice of rank one and V_L^+ be the fixed points of the lattice VOA V_L associated to L under an automorphism of V_L lifting the -1$ isometry of…
