Abstract
In the framework of noncommutative geometry we describe spinor fields with nonvanishing winding number on a truncated (fuzzy) sphere. The co rresponding field theory actions conserve all basic symmetries of the standard commutative version (space isometries and global chiral symme try), but due to the noncommutativity of the space the fields are regu larized and they contain only a finite number of modes.
