Some calculus with extensive quantities:
wave equation

Anders Kock and Gonzalo E. Reyes

We take some first steps in providing a synthetic theory of distributions. In particular, we are interested in the use of distribution theory as foundation, not just as tool, in the study of the wave equation.

Keywords: distribution, wave equation, synthetic differential calculus, extensive quantity
