Expressions of algebra elements and transcendental noncommutative calculus
Ideas from deformation quantization are applied to deform the expression of
elements of an algebra. Extending these ideas to certain transcendental
elements implies that \frac{1}{i\h}uv in the Weyl algebra is naturally viewed
as an indeterminate living in a discrete set {\it or}
. This may yield a more mathematical understanding of
Dirac's positron theory
