  • Preservers of unitary group or equivalence by unitaries
    Petek, Tatjana ; Radić, Gordana
    We give the complete description of bijective real-linear transformations on ▫$\mathscr{B(H)}$▫, the algebra of all bounded linear operators on an infinite-dimensional complex Hilbert space ... ▫$\mathscr{H}$▫, where every unitary ▫$U \in \mathscr{B(H)}$▫ is mapped to a unitary ▫$\phi (U)$▫. In turn, bijective real-linear maps on ▫$\mathscr{B(H)}$▫ preserving equivalence by unitaries will be determined.
