When the image ImA of a linear operator to be inverted is not closed, then the inverse A
–1
, or the generalized inverse A
†
, is not defined everywhere on
and is not continuous. This is the case, for example, with non-degenerate (or non-finite rank) compact operators, and it's easy to see that the number of conditions in the problem is infinite. Appropriate solution techniques are then required,...
