概要

• 論文の詳細を見る

• Non-singular instantons are shown to exist on noncommutative R^4 in U(1) gauge theory. Their existence is primarily due to the noncommutativity of the coordinates. The integer instanton number on the noncommutative R^4 be understood as winding number of the U(1) gauge field as well as dimension of a certain projection operator acting on the representation space of the noncommutative coordinates.
