You should read this page; under Linux those are in the 'Real Time signals' block and
Quote:
Linux supports real-time signals as originally defined in the POSIX.1b real-time extensions (and now included in POSIX.1-2001). Linux supports 32 real-time signals, numbered from 32 (SIGRTMIN) to 63 (SIGRTMAX). (Programs should always refer to real-time signals using notation SIGRTMIN+n, since the range of real-time signal numbers varies across Unices.)

Unlike standard signals, real-time signals have no predefined meanings: the entire set of real-time signals can be used for application-defined purposes. (Note, however, that the LinuxThreads implementation uses the first three real-time signals.)
