If there were no friction a knot could not hold together. However, that really wouldn't matter since there would be no way you could handle or pull on the ends of the rope to make a knot in the first place.

You can tie a knot without friction (assuming you can still grip the rope) because the rope gets tangeled together. Two pieces of rope are trying to occupy the same space in effect as you pull tighter. However, friction makes it hard to take a knot apart. You have to overcome the frictional force to pull apart the knot. Without friction, the knot would come apart very easily.

You can tie the knot - it just won't hold anything - so what's the definition of a knot?
Note recent developments in fishing line to make it stronger, lighter, and knot-free have necessitated learning new knots and fastening methods.

I think it would depend on the knots. They could hold, however, they may not be able to hold as well as with friction.

A wedding knot - no knots- no tying- no friction.

Yes. If we could somehow completely eliminate friction, no two things would ever be able to touch each other. Even if we could somehow use our hands to touch the rope or string, it would neve get "tangled" together as the guy above me said. This tangling can't happen if the two parts can't even touch each other.
