[https://doi.org/10.1080/03081088708817829]In this paper we generalise the well-known Gauss algorithm for counting primitive representations of positive integers by positive definite ternary quadratic forros ([3], Arts 278-292) to the case of quadratic forros in k variables. Our main considerations are based on the systematic use of exterior algebra which, in our opinion, simplifies thewhole treatment and helps to understand sorne apparently hidden ideas.19 p.application/pdfeng(c) Angela Arenas, 1986Anàlisi funcionalUniversitat de Barcelona.
