Cycles of linear and semilinear mappings
We give a canonical form of matrices of a cycle of linear or semilinear
mapping V_1 --- V_2 --- ... --- V_t --- V_1 in which all V_i are complex vector
spaces, each line is an arrow ---> or <---, and each arrow denotes a linear or
semilinear mapping.Comment: 18 page
The finite harmonic oscillator and its associated sequences
A system of functions (signals) on the finite line, called the oscillator
system, is described and studied. Applications of this system for discrete
radar and digital communication theory are explained.

Octonionic Mobius Transformations
A vexing problem involving nonassociativity is resolved, allowing a
generalization of the usual complex Mobius transformations to the octonions.
This is accomplished by relating the octonionic Mobius transformations to the
Lorentz group in 10 spacetime dimensions. The result will be of particular
interest to physicists working with lightlike objects in 10 dimensions.Comment: Plain TeX, 12 pages, 1 PostScript figure included using eps
