Cone-parameter convolution semigroups and their subordination. (English) Zbl 1039.43004
The authors give a characterization of cone-parameter convolution semigroups, which are connected with the Lévy-Khintchine representation. Some examples are discussed. Subordination of cone-parameter convolution semigroups by cone-valued cone-parameter convolution semigroups is introduced with its general description. This is an extension of Bochner’s subordination.
