This project is mathematical research in operator theory, a                subject that had its origins in quantum mechanics (where                        operators on Hilbert space are used in place of scalars to                      represent physical quantities), but that has long since acquired                a vigorous life of its own.  The world of operators, being                      infinite-dimensional and noncommutative, is full of remarkable                  phenomena that are not present in the more familiar world of                    scalars.                                                                             More specifically, Professor Herrero will work on problems                 related to compact perturbations and approximation of Hilbert                   space operators, including approximation by similarity -                        invariant classess of operators and closures of joint similarity                orbits.  He will also study the spectral structures of                          multicyclic operators.
