| Abstract: | We are concerned with the so-called  -pseudo-differential calculus. We describe the spectrum of the unital and commutative  -algebra given by the norm closure of the space of  -order pseudo-differential operators modulo compact operators; other related algebras are also considered. Finally, their  -theory is computed. |
| Keywords: | $K$-theory $C^\ast$-algebras pseudo-differential operators |
