We study the 0 + 1 dimensional Chern-Simons theory at finite temperatu
re within the framework of the derivative expansion. We obtain various
interesting relations, solve the theory within this framework and arg
ue that the derivative expansion is not a suitable formalism for a stu
dy of the question of large gauge invariance. [S0556-2821(98)06320-6].
