https://doi.org/10.1007/978-3-663-13498-5We begin by applying Theorem 3.42 and Corollary 3.44 to the Fredholm theory of Toeplitz operators. Although this chapter is concerned with Toeplitz operators on H. ? 1., we first state some results for Toeplitz operators on H. and 1., because there do not arise any substantial difficulties when passing from the case . = 2 to the case . ≠ 2.

Leistungszusage bei Sicherheit,Throughout this chapter we let L. and L. (1≤P≤∞) refer to the L. spaces of Lebesgue measure on ? and ?., respectively. The L. spaces on the unit circle will be denoted by L.(T). The operator . defined by.:L.→L.., . ? . | ?.is clearly bounded for 1 ≤ . ≤ ∞.

Symbol analysis,Let . be a closed subset of . = .(L.) and let . ∈ L.. The matrix function . is called . if there exist a real number . > 0 and two invertible matrices ., . ∈ ?. such that Re (.(.) .) ≧ . for all . ∈ ., that is,.and . is said to be . if.that is, if each matrix in the closed convex hull of .(.) is invertible.

Toeplitz operators on l,,We have already settled the Fredholm theory of the operators in alg (Corollaries 4.7 and 4.8) and stated a localization result for Toeplitz operators on l. (Theorem 2.95). This chapter is devoted to some more delicate questions of the l.. theory of Toeplitz operators.
