Magnetic Monopoles and Abelian Gauge Fixing in SU(4) Gauge Group.

Abelian gauge fixing procedure is used to create the SU(4) magnetic monopoles in the vicinity of the points where the gluon field becomes singular. The matrix of the scalar field is considered as almost diagonal in the SU(2) and SU(3) subspaces. The gauge transformation which diagonalizes the hedgehog filed, transforms the gluon field into two regular and singular parts. The abelian magnetic monopoles which appear in the latter part obey the quantization condition. [ABSTRACT FROM AUTHOR]
