HompH0,H1q denote the subset of Fredholm operators, topologized with the norm topology. The closed range condition is redundant [Pa1, §VII], but as cokerT is not Hausdorﬀ if T is not closed range it seems sensible to include it as part of the deﬁnition. The numerical index of a Fredholm operator is deﬁned as (9.7) indT “ dimkerT

By definition, is a semi-Fredholm operator if is closed (i.e. it is a normally-solvable operator) and at least one of the vector spaces and is of finite dimension. (The definition is partially redundant, since if the dimension of is finite, is closed.) For a semi-Fredholm operator, its index, i.e.

Let X, Y be Banach spaces over either the real field or the complex field. A continuous linear operator will be called a generalized Fredholm operator if T\X) is closed in Y, and Ker T and Coker T are reflexive Banach spaces. In Kohn and Nirenberg showed, that the ellipticity of a classical smooth pseudodifferential operator is necessary for its Fredholm property. Apart from necessary conditions Kumano‐go gave in [ 11 , Chapter III, Theorem 5.16] sufficient conditions for the Fredholmness of smooth pseudodifferential operators. trum of an operator is in general more complicated.
