Spatial quantales
The paper gives an appropriate notion of a prime element of a quantale and characterizes spatial quantales as those quantales having enough primes. This result solves a problem stated by \textit{J. W. Pelletier} and the reviewer [``Simple involutive quantales'', J. Algebra 195, 367-386 (1997; Zbl 0894.06005)].
