The quantum many body problem has been at the heart of much of theoretical and experimental physics over the past few decades ...

In the Hilbert space L A 2 ( I;E )( I:=[ a,b ),−∞ 0 ) , the maximal dissipative singular matrix-valued Sturm–Liouville operators that the extensions of a minimal symmetric operator with maximal ...

Abstract.In this paper, we characterize the matrix classes (𝓁₁, ℓ p λ ) (1 ≤ 𝒫 < ∞). We also obtain estimates for the norms of the bounded linear operators 𝐿𝐴 defined by these matrix ...
