Summary: STATEMENT OF RESEARCH
MOHAMED AIT NOUH
Introduction: My field of study is knot theory. A knot (resp. link) k is a smooth embedding of
S1 (resp. a disjoint union of circles) in S3 = R3 {} (e.g. the most basic knots are depicted in Fig. 1).

I am interested in the interplay between knot theory and dimension four topology and geometry, via
twisting operations. To define a twisting operation, we need to define Dehn surgery.
Dehn surgery: (see Figure 2) Let N(k) be a tubular neighborhood of a knot k the S3. Then a
3-manifold obtained by
