Abstract
The noncommutative soliton is characterized by the use of the projection operators in non-commutative space. By using the close relation with the K-theory of -algebra, we consider the variations of projection operators along the commutative directions and identify their topological charges. When applied to the string theory, it gives the modification of the brane charges due to tachyon background.
