Gerhard Lagaly,F. Horst Müller,Armin Weiss previous argument is not a proof in the usual sense, and another proof has to be found, typically a combinatorial argument involving only intrinsically finite objects. Unfortunately (or fortunately...), no such proof is known to date, and it is only known that such a proof, if it exists, has to be very complicated in some sense.

Entwicklung des Containerverkehrs,So far we have described several examples of LD-systems: conjugacy of a group, braid exponentiation, injection bracket. . this chapter, we give new examples, and mention some general results about LD-systems, and about those special families obtained by prescribing additional identities.

Orders on Free LD-systemsHere, we begin our study of free LD-systems, which will be continued in the following four chapters. The main result of this chapter is that every free LD-system admits a canonical linear ordering. We deduce a solution for the word problem of left self-distributivity, and a simple criterion for recognizing free LD-systems.

At this early stage, some of the constructions may look artificial or strange: it will be one of the aims of the subsequent chapters, in particular in Part B of

https://doi.org/10.1007/978-3-658-13126-5 aim is to introduce a specific combinatorial technique, called word reversing, which is needed in Chapter III to extend the braid action of Chapter I on LD-systems. The third aim is to develop the techinque of word reversing in a general framework, so as to be able to apply it to a certain group.in

Here we follow Burckel’s approach, which associates with every positive braid a normal form consisting in a finite tree; the order of positive braids is then a lexicographical ordering for the a
