 note = {In this paper we consider a class of pseudodifferential operators of Kohn-Nirenberg type, and make a remark on approximate formula for those pseudodifferential operators. Moreover, we also consider asymptotic expansion for pseudodifferential operators of the same kind. The explicit representation of the approximate formula can be given by the pseudodifferential operators with standard symbol replaced by an approximate sequence of symbols. While, the asymptotic expansion formula provides us with a tractable method of operations of seudodifferential operators, because the infinite series in the expansion may be convergent in the appropriate topology of symbol class., text, application/pdf},
