in this paper, we find explicit solution to the operator equation$txs^* -sx^*t^*=a$ in the general setting of the adjointable operators between hilbert $c^*$-modules, when$t,s$ have closed ranges and $s$ is a self adjoint operator.
We consider the transitive linear maps on the operator algebra $B(X)$for a separable Banach space $X$. We show if a bounded linear map is norm transitive on $B(X)$,then it must be hypercyclic with strong operator topology. Also we provide a SOT-transitivelinear map without being hypercyclic in the strong operator topology.
در این پایان نامه مرکز ساز جبرهای عملگری استاندارد وh^*- جبرهای نیم ساده را بیان می کنیم. فرض کنیم a یک *h-جبر نیم ساده و t: a -> a یک نگاشت جمعی باشد به طوری که به ازای هر x∈a و بعضی n ≥ 1 داشته باشیم. 2t(x n+1) = t(x)xn + xnt(x) در این صورت t یک مرکزساز چپ و راست است. این پایان نامه بر اساس مقاله ی زیر نوشته شده است: i. kosi-ulbl and j. vukman, on centralizers of standard operator algebras ...
در این رساله، ابتدا مفهوم *c- جبر را بیان می کنیم، سپس با تجزیه و تحلیل دقیق مقاله های dr. alexander a. katz, a note on two-sided ideals in locally c?-algebras, apr 2013. dr. a. a. katz,dr. o. friedman, on projective limits of real c?- and jordan operator algebras, oct 2005. مفهوم *c- جبرموضعی و قیاس های ژوردان و حقیقی از *c- جبرهای موضعی مختلط بیان می شود. در نهایت نشان می دهیم که اگر a یک ...
the purpose of this paper is to introduce the concept of l-fuzzybilinear operators. we obtain a decomposition theorem for l-fuzzy bilinearoperators and then prove that a l-fuzzy bilinear operator is the same as apowerset operator for the variable-basis introduced by s.e.rodabaugh (1991).finally we discuss the continuity of l-fuzzy bilinear operators.
the main purpose of this paper is to detemine the fine spectrum of the generalized difference operator delta_{uv} over the sequence space c0. these results are more general than the fine spectrum of the generalized difference operator delta_{uv} of srivastava and kumar.
in this paper, using a generalized dunkl translation operator, we obtain a generalization of titchmarsh's theorem for the dunkl transform for functions satisfying the$(psi,p)$-lipschitz dunkl condition in the space $mathrm{l}_{p,alpha}=mathrm{l}^{p}(mathbb{r},|x|^{2alpha+1}dx)$, where $alpha>-frac{1}{2}$.
In this paper, we study some properties of analytic extension of a $n$th roots of $M$-hyponormal operator. We show that every analytic extension of a $n$th roots of $M$-hyponormal operator is subscalar of order $2k+2n$. As a consequence, we get that if the spectrum of such operator $T$ has a nonempty interior in $mathbb{C}$, then $T$ has a nontrivial invariant subspace. Finally, w...
Let $G$ be a locally compact group, $H$ be a compact subgroup of $G$ and $varpi$ be a representation of the homogeneous space $G/H$ on a Hilbert space $mathcal H$. For $psi in L^p(G/H), 1leq p leqinfty$, and an admissible wavelet $zeta$ for $varpi$, we define the localization operator $L_{psi,zeta} $ on $mathcal H$ and we show that it is a bounded operator. Moreover, we prove that the localizat...
in this note we characterize the compact weighted frobenius-perron operator $p$ on $l^1(sigma)$ and determine their spectra. we also show that every weakly compact weighted frobenius-perron operator on $l^1(sigma)$ is compact.
