Résumé :
Labeling schemes, a subject closely related to induced and induced universal graphs, have been studied extensively in the theoretical computer science community over the last 2 decades.
In my talk I will introduce the concept and present new results for graphs of bounded degree ∆. In particular I will present the following results:

1. An optimal log n + O( log ∆) adjacency labeling scheme for bounded degree trees.

2. An optimal (⌊∆⌋/2+1)logn adjacency labeling scheme for general bounded degree graphs.

3. An improved adjacency labeling scheme for general graphs with bounded degree √(n) < ∆ ≤ n/5 (using combinatorial number system).

The talk will conclude with a survey of open problems in the field.
