    Graduate Does the inverse of this special matrix have a power series expansion?

    Thanks. Is it true that det|I+A|=1+trace(A)+det|A| ? If not then is there any general expression for det|I+A|

    Graduate Does the inverse of this special matrix have a power series expansion?

    Hi...can anyone please suggest whether the following inverse has a power series expansion (I+\delta A)^{-1} where \delta is a constant and A = \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...
