英文摘要
The smooth unknotting conjecture in dimension four is reduced to the case which is connected by a one-parameter family with one intersection point to the unknot, by assuming our Markov type theorem. Moreover, since the reduced case can be studied by a kind of tree type Cayley diagram for the corresponding word problem, the conjecture is expected to be proved in a near future.
