* To Dr. T. H. Goodspeed, Professor of Botany and Director of the Botanical Garden, University of California, the author expresses her sincere gratitude both for counsel and for extending every research facility, including seeds of most of the Nicotiana cultures investigated. In addition she acknowledges with pleasure seeds sent her by E. E. Cheel, J. M. Black, Professor J. B. Cleland and Hazel Pearce. t Kostoff10"I has given a 32-paired race which he has grown the designation "N. Eastii." The author does not consider this and another 32-paired race sufficiently distinct from N. suaveolens morphologically to warrant separation. 1 Goodspeed, T. H. (in press), Univ. Calif. Pubi.

Some Applications of Operator-valued Herglotz Functions
We consider operator-valued Herglotz functions and their applications to self-adjoint perturbations of self-adjoint operators and self-adjoint extensions of densely defined closed symmetric operators. Our applications include model operators for both situations, linear fractional transformations for Herglotz operators, results on Friedrichs and Krein extensions, and realization theorems for cla...
متن کاملError bounds in approximating n-time differentiable functions of self-adjoint operators in Hilbert spaces via a Taylor's type expansion
On utilizing the spectral representation of selfadjoint operators in Hilbert spaces, some error bounds in approximating $n$-time differentiable functions of selfadjoint operators in Hilbert Spaces via a Taylor's type expansion are given.
متن کاملA note on $lambda$-Aluthge transforms of operators
Let $A=U|A|$ be the polar decomposition of an operator $A$ on a Hilbert space $mathscr{H}$ and $lambdain(0,1)$. The $lambda$-Aluthge transform of $A$ is defined by $tilde{A}_lambda:=|A|^lambda U|A|^{1-lambda}$. In this paper we show that emph{i}) when $mathscr{N}(|A|)=0$, $A$ is self-adjoint if and only if so is $tilde{A}_lambda$ for some $lambdaneq{1over2}$. Also $A$ is self adjoint if and onl...
متن کاملAn analytic solution for a non-local initial-boundary value problem including a partial differential equation with variable coefficients
This paper considers a non-local initial-boundary value problem containing a first order partial differential equation with variable coefficients. At first, the non-self-adjoint spectral problem is derived. Then its adjoint problem is calculated. After that, for the adjoint problem the associated eigenvalues and the subsequent eigenfunctions are determined. Finally the convergence ...
متن کاملA Generalized Sturm Theory for Indefinite Elliptic Systems
Sturm results on oscillation and comparison for solutions of a second-order differential equation have a topological nature in their own. Roughly speaking they describe the rotation of a straight line in the phase plane of the equation. Many generalization of this results were obtained; among the others we recall the symplectic version due to Arnol’d in [2] for second order hamiltonian systems ...
