Hi...can anyone please suggest whether the following inverse has a power series expansion(adsbygoogle = window.adsbygoogle || []).push({});

[tex](I+\delta A)^{-1}[/tex]

where [tex]\delta [/tex] is a constant and [tex] A = [/tex]

[tex] \begin{pmatrix} T & T-1 & T-2 &... & 3 & 2 & 1\\ T-1 & T-1 & T-2 & ... & 3 & 2 & 1 \\ .. \\2 & 2 & 2 &... & 2 & 2 & 1 \\ 1 & 1 & 1 & ... & 1 & 1 & 1 \end{pmatrix} [/tex]

Thanks!
