Some aspects of Golden-Thompson type inequalities for a boson system with finite degrees of freedom are reviewed.Then a general class of boson-fermion systems with finite degrees of freedom, including supersymmetric ones, is considered.Functional integral representations for the partition function as well as related objects of a boson- fermion system are derived and applied to obtain Golden-Thompson type inequalities.The present article is intended to be a review paper, but, includes new results which are extensions of some results obtained in a previous paper (A.Arai, Rev.
