RT Journal Article T1 An extension of a theorem of Domar on invariant subspaces A1 Gallardo Gutiérrez, Eva A. A1 Partington, J.R. A1 Rodriguez, D. J. AB A remarkable theorem of Domar asserts that the lattice of the invariant subspaces of the right shift semigroup {S-tau}(tau >= 0) in L-2 (R+, w(t)dt) consists of just the " standard invariant subspaces" whenever w is a positive continuous function in R+ such that PB Univ.
