First Page The calculus we have given here is exact modulo operators in L1 and symbols in S1. However, it is complicated by the presence of in nite sums in (2.1.14). Now the terms with 6= 0 in these sums are of order m+ 1 2ˆ.
A Fourier integral operator is an operator of the form (1.5) (&u)(x)= j j exv(iif(x,y,l))p(x,y, l)u{y)dydl. Here χ e Ω, с л"1, ^ e ύ 2 с R"2, ξ e RN and м е Со(П 2). The function ρ is called the symbol and φ the phase function of the operator^. The theory of pseudo differential operators, discussed in § 1, is well suited for investigating various problems connected with elliptic differential equations. However, this theory fails to be adequate for studying equations of hyperbolic type, and one is then forced to examine a wider class of operators, the so-called Fourier integral operators (Egorov [1975], Hormander [1968, 1971, 1983 INVARIANT FOURIER INTEGRAL OPERATORS ON LIE GROUPS B0RGE P. D. NIELSEN and HENRIK STETKvER 1. Introduction.
Thus, the boundedness of zero-order Fourier integral operators on L2 (Hormander [ 5 ] ) yields T’ :L + L k for 9 8 r = 0, with norm independent of 4~ r.
