Unipodal and Bicomplex Internet References

This page presents a number of Internet references to papers on the topics of unipodal algebra (or unipodal numbers), bicomplex numbers, hyperbolic numbers, split-complex numbers, perplex numbers, hypercomplex numbers. These number systems (mostly) have in common that they are (usually commutative) rings with one unipotent number u, that is, a number that is not a real number, but that squares to unity (u²= 1). Most of these systesms have two or more distinct unit imaginary numbers. The unipodal algebra is formed from the linear combinations of {1, u} over the complex numbers. The bicomplex numbers are formed by the linear combinations of {1, i, j, ij} over the real numbers, where ij=u. Then, appropriate multiplications are defined on these elements to ensure closure.
