The notions of move functionality and attribute features proved to be primary within the final fifty years in operator concept and in process thought. Moshe Livsic performed a principal function in constructing those notions, and the publication features a number of rigorously selected refereed papers devoted to his reminiscence. themes comprise classical operator concept, ergodic concept and stochastic methods, geometry of gentle mappings, mathematical physics, Schur research and procedure concept. the range of issues attests good to the breadth of Moshe Livsic's mathematical imaginative and prescient and the deep influence of his work.

The booklet will entice researchers in arithmetic, electric engineering and physics.

Asset situation, info platforms and choice types, is the second one quantity of the Engineering Asset administration overview sequence. The manuscripts supply examples of implementations of asset info structures in addition to a few useful functions of situation info for diagnostics and prognostics. The expanding development is in the direction of prognostics instead of diagnostics, for this reason the necessity for evaluation and selection types that advertise the conversion of info into prognostic details to enhance life-cycle making plans for engineered resources.

Let V (z) ∈ SL−1 0 (R). 1). Proof. 12) τ τ τ H+ ⊂ L2 [0, +∞) ⊂ H− C Inverse Stieltjes-like Functions and Schr¨ odinger Systems 33 such that V (z) = VΘΛ (z). 6). 5). 7). The operator K τ in the above system (see [11], [13]) is deﬁned by K τ c = c · α, (K τ )∗ x = (x, α) τ τ c ∈ C, α ∈ H− , x(t) ∈ H+ . τ In addition we can observe that the function η(λ) ≡ 1 belongs to H− . To conﬁrm this we need to show that (x, 1) deﬁnes a continuous linear functional for every τ x ∈ H+ . It was shown in [11], [12] that τ = D(Λ0τ ) H+ c1 1 + t2 c2 t 1 + t2 c1 , c2 ∈ C.

Much of the development of this theory, including the lifting theorem for intertwining operators and the parametrization of the possible lifts, can be viewed as exploiting and reﬁning the structure theory of isometric operators on complex Hilbert space. The study of commuting n-tuples of isometries is not so simple, even for n = 2. This paper makes a contribution to this theory. The starting point is the model introduced implicitly in [1] for a bi-isometry or a pair of commuting isometries. We now describe the model explicitly.

Y(a) − y (a) = 0 It is well known [1] that A = A∗ . The following theorem was proved in [6]. 3. 6) 1 [y (a) − hy(a)] [μδ(x − a) + δ (x − a)]. 5) and all real numbers μ ∈ [−∞, +∞]. 4. An operator T with the domain D(T ) and ρ(T ) = ∅ acting on a Hilbert space H is called accretive if Re (T f, f ) ≥ 0, ∀f ∈ D(T ). V. R. 5. An accretive operator T is called [22] α-sectorial if there exists a value of α ∈ (0, π/2) such that cot α |Im (T f, f )| ≤ Re (T f, f ), f ∈ D(T ). An accretive operator is called extremal accretive if it is not α-sectorial for any α ∈ (0, π/2).
