We introduce the notion of a tight cylinder over an ane variety and show the
eect of tightness on the automorphism group. We present various criteria of
tightness, give examples of tight cylinders (conguration spaces, discriminant
varieties), and describe their automorphism groups.
The talk is based on a joint work with Vladimir Lin (Technion, Haifa).
