  The fragmentation equation is commonly expressed in terms of two functions,
the rate of fragmentation and the mean number of fragments. In the case of
binary fragmentation an alternative description is possible based on the
fragmentation kernel, a function from which the rate of fragmentation and the
mean distribution of fragments can be obtained. We extend the fragmentation
kernel to multinary/multicomponent fragmentation and derive expressions for
certain special cases of random and non random fragmentation.
