Exact solutions of fragmentation equations with general fragmentation rates and separable particles distribution kernels (Q1719134)

Summary: We make use of Laplace transform techniques and the method of characteristics to solve fragmentation equations explicitly. Our result is a breakthrough in the analysis of pure fragmentation equations as this is the first instance where an exact solution is provided for the fragmentation evolution equation with general fragmentation rates. This paper is the key for resolving most of the open problems in fragmentation theory including ``shattering'' and the sudden appearance of infinitely many particles in some systems with initial finite particles number.
