Let V(x) ≧ 0 be given on Rn and defineThis constant has played a role in many investigation. For n — 3 it was shown in Courant-Hilbert [7] p. 446 that In [10], Kato estimates C2,2,2,ƛ(V) in terms of the L2 +L∞ norm of V in R3. Stummel [22] showed that C2,2,2,1(V) is bounded by in Rn, n > 2, provided α < 4. Browder [6] and Balslev [3] showed that

MULTIPLE OPERATIONS FOR STRABISMUS
Australian and New Zealand Journal of Ophthalmology, 1980Some examples will be noted where the strabismus surgeon plans the patient to have more than one operation. Unfortunately most multistage strabismus procedures are unplanned and are a consequence of failure of the initial surgery. The three most common causes of such failure will be discussed.

Classes of Multiplication Operators and Their Limit Operators
Zeitschrift für Analysis und ihre Anwendungen, 2004Limit operators have proven to be a device for the study of several properties of an operator including Fredholmness and invertibility at infinity, but also the applicability of approximation methods. For band-dominated operators, the question of existence and structure of their limit operators essentially reduces to the study of multiplication ...

Multiplication Operators on the Bergman Space
Lecture Notes in Mathematics, 2015 This book deals with various aspects of commutants and reducing subspaces of multiplication operators on the Bergman space, along with relevant von Neumann algebras generated by these operators, which have been the focus of considerable attention from ...

A-Poset with Multiplicative Operation
2015In this paper we will prove that the new structure called A-poset, defined by Fric and Skřivanek (Generalized random events, 2015) is equivalent to D-posets and effect algebras. In next section we introduce a multiplicative operation on A-postes and prove that these two structures are isomorphic.

Multiplication operator on a matrix polynomial
Ukrainian Mathematical Journal, 1992Summary: It is shown, how the study of the perturbed multiplication operator by a matrix polynomial in the space \(L_ 2(\mathbb{R},\mathbb{C}^ n)\) can be reduced to the study of the perturbed multiplication operator by the independent variable in the space \(L_ 2(\mathbb{R},\omega,\mathbb{C}^ n)\) with weight \(\omega\), fulfilling the Muckenhoupt ...
