- Write as many criterion as you can which can be used to check if an operator is invertible.
- Check if the operator \(A\) on \(C^3\) defined below is invertible. \begin{equation*} A\begin{pmatrix} x_1 \\ x_2 \\x_3 \end{pmatrix} = \begin{pmatrix} x_2 \\ x_3 \\x_1 \end{pmatrix} \end{equation*}

\(\S\S\) 7.3 Q[1] \(\int_0^\infty\frac{1}{(x^2+p^2)^2} dx \)Node id: 1566pageFull details are written out for this problem. This includes a proof that certain integrals vanish when Darboux theorem is used. In solutions to all other similar problems of this section, some of these details, being repetitive in nature, are suppressed. It is hoped that, if required, the reader will be able to supply the details by consulting this solution with full details. |
