Remarks on Hyponormal Operators and Almost Normal Operators
In 1984 M. Putinar proved that hyponormal operators are subscalar operators of order two. The proof provided a concrete structure of such operators. We will use this structure to give a sufficient condition for hyponormal operators T with trace-class commutator to admit a direct summand S so that T ⊕ S is the sum of a normal operator and a HilbertSchmidt operator. We investigate what this suffi...
متن کاملRemarks on Quantum Differential Operators
In the course of writing the book [9] and various papers [10, 11, 12, 13, 14, 15, 16] we encountered many q-differential equations but were frustrated by a lack of understanding about natural forms for such equations. One has operators of the type qKP or qKdV for example but even there, expressing the resulting equations (even via Hirota type equations or in bilinear form) seemed curiously diff...
متن کاملRemarks on normal bases
We prove that any Galois extension of commutative rings with normal basis and abelian Galois group of odd order has a self dual normal basis. Also we show that if S/R is an unramified extension of number rings with Galois group of odd order and R is totally real then the normal basis does not exist for S/R.
متن کاملRemarks on the Spectrum of Bounded and Normal Operators on Hilbert Spaces
Let H be a complex Hilbert space H . Let T be a bounded opertor on H , and let λ be a scalar. We set Tλ := T − λI . We introduce the concept of Tλ−spectral sequence in order to discuss the nature of λ when λ belongs to the spectrum of T. This concept is used to make new proofs of some classical and well-known results from general spectral theory. This concept is also used to give a new classifi...
متن کاملREMARKS ON LIPSCHITZ p-SUMMING OPERATORS
In this note, a nonlinear version of the Extrapolation Theorem is proved and as a corollary, a nonlinear version of the Grothendieck’s Theorem is presented. Finally, we prove that if T : X → H is Lipschitz with X being a pointed metric space and T (0) = 0 such that T∣H∗ is q-summing (1 ≤ q <∞), then T is Lipschitz 1-summing.
