The dot product formula allows one to measure an angle determined by two vectors, and a formula known to Euler and Lagrange outputs the measure of a solid angle in R3 given its three spanningâ€¦ (More)

Motivated to better understand the wonderful artistry and hyperbolic tessellations of M.C. Escherâ€™s Circle Limit prints, we study the isometries of the hyperbolic plane and create tessellations ofâ€¦ (More)

We provide a simple construction for a matrix representation of the Gale transform of a simplotope, the Cartesian product of simplices. The matrix representation is a Kronecker product of matricesâ€¦ (More)
