    • Hilbert points in Hilbert space-valued $L^p$ spaces 

      Brevig, Ole Fredrik; Grepstad, Sigrid (Peer reviewed; Journal article, 2023)
      Let H be a Hilbert space and (Ω,F ,µ) a probability space. A Hilbert point in L p (Ω;H) is a nontrivial function ϕ such that ∥ϕ∥p ≤ ∥ϕ+f ∥p whenever ⟨f ,ϕ⟩ = 0. We demonstrate that ϕ is a Hilbert point in L p (Ω;H) for ...
