摘要：Quotient modules are important objects in multivariable operator theory. For quotient modules in H2(D2), Yang defined the fringe operator and studied its properties, recently Luo, Izuchi and Yang proved that the fringe operator is Fredholm if and only if the restriction pair (Rz1 , Rz2 ) is, and  ind(F) = −ind(R − λ).  In this lecture we define the fringe operator pair for quotient modules in H2(D3), and show that the fringe operators operator F is Fredholm if and only if the restriction triple R− λ is Fredholm where λ ∈ D3, and get a similar index formula.
