Symmetry equipment have lengthy been famous to be of serious value for the examine of the differential equations. This booklet offers an excellent advent to these purposes of Lie teams to differential equations that have proved to be helpful in perform. The computational equipment are awarded in order that graduate scholars and researchers can with no trouble discover ways to use them. Following an exposition of the purposes, the publication develops the underlying conception. a few of the themes are offered in a singular method, with an emphasis on specific examples and computations. additional examples, in addition to new theoretical advancements, look within the routines on the finish of every bankruptcy.

Example text

14b shows that a repetitive sequence can contain several firings of the same transition (while still being minimal). The 1T2 T1 T3 initial marking m 0 = (1, 1, 0, 0) is such that m 0 T  m 0. The sequence S 4 =  T 1T 2T 1T 3 is thus repetitive. This sequence contains transition T 1 twice (and none of its proper prefixes is repetitive). Since S 4 is complete and stationary repetitive, the PN is consistent. 14 Illustration of repetitive sequences. 3 Let L (m 0) be the set of firing sequences from the initial marking m0.

This PN would thus be bounded with this initial marking. 3a shows that the PN is bounded whatever m0 (irrespective of the evolution, the number of tokens remains constant). An unmarked PN is said to be structurally bounded if for all initial finite marking, the marked PN is bounded. 1 If a PN is unbounded for m 0, it is unbounded for m 0  m 0. 2. The concept of a bounded PN applies to all the abbreviations and extensions. The concept of a safe PN could apply to all the abbreviations and extensions (but with slight differences), with the exception of the continuous PNs since the place markings are not integers.

5). 3 MODELING OF SOME CONCEPTS One of the key features of Petri nets is their capacity to graphically present certain relations and to visualize certain concepts. We shall give some examples of this below. 14a, we clearly see that after transition T 1 has been fired and until transition T2 is fired, there are concurrent evolutions, from place P1 to place P3 on the one hand and from place P 2 to place P 4 on the other. Each of these two evolutions can be carried out at its own pace. 14b, place P 1 models the availability of a resource which can be used by the lefthand part as from the firing of T 1 and up to the firing of T 2 or by the righthand part in similar conditions, but not by both at the same time (resource sharing).
