Convergence of Random Products of Projections Under Infinite-Periodic Selections

Rasoul Eskandari, Mohammad Sal Moslehian

Let ${P_{j}}$ be a sequence of projections onto the closed subspaces $M_{j}$ of a Hilbert space $H$ . Consider an infinite sequence $P_{i_{1}}, P_{i_{2}}, \dots$ with…

Conjugations on Hilbert $C^{*}$ -modules

Mahboubeh Faregh, Rasoul Eskandari, Mohammad Sal Moslehian

This work initiates a systematic development of conjugation theory within the framework of Hilbert $C^{*}$ -modules, extending classical complex symmetric operator theory beyond the H…

Separated Pairs of Submodules in Hilbert $C^{*}$ -modules

R. Eskandari, W. Luo, M. S. Moslehian +2

We introduce the notion of the separated pair of closed submodules in the setting of Hilbert $C^{*}$ -modules. We demonstrate that even in the case of Hilbert spaces this concept has…

Convergence of Random Products of Countably Infinitely Many Projections

Rasoul Eskandari, Mohammad Sal Moslehian

Let $r \in N \cup {\infty}$ be a fixed number and let $P_{j} (1 \leq j \leq r)$ be the projection onto the closed subspace $M_{j}$ of $H$ . We are inter…

Pedersen--Takesaki operator equation in Hilbert $C^{*}$ -modules

R. Eskandari, X. Fang, M. S. Moslehian +1

We extend a work of Pedersen and Takesaki by giving some equivalent conditions for the existence of a positive solution of the so-called Pedersen--Takesaki operator equation $XHX=K…

Hilbert $C^{*}$ -module independence

R. Eskandari, J. Hamhalter, M. S. Moslehian +1

We introduce the notion of Hilbert $C^{*}$ -module independence: Let $A$ be a unital $C^{*}$ -algebra and let $E_{i} \subseteq E, i = 1, 2$ , be ternary subspa…

B-spline interpolation problem in Hilbert C*-modules

Rasoul Eskandari, Michael Frank, Vladimir Manuilov +1

We introduce the $B$ -spline interpolation problem corresponding to a $C^{*}$ -valued sesquilinear form on a Hilbert $C^{*}$ -module and study its basic properties as well as the uniquene…

Operator equalities and Characterizations of Orthogonality in Pre-Hilbert $C^{*}$ -Modules

Rasoul Eskandari, M. S. Moslehian, Dan Popovici

In the first part of the paper, we use states on $C^{*}$ -algebras in order to establish some equivalent statements to equality in the triangle inequality, as well as to the parallelo…

Extensions of the Lax-Milgram theorem to Hilbert C*-modules

R. Eskandari, M. Frank, V. M. Manuilov +1

We present three versions of the Lax-Milgram theorem in the framework of Hilbert C*-modules, two for those over W*-algebras and one for those over C*-algebras of compact operators.…

Operator equations $A X + Y B = C$ and $A X A^{} + B Y B^{} = C$ in Hilbert $C^{*}$ -modules

Z. Mousavi, R. Eskandari, M. S. Moslehian +1

Let $A, B$ and $C$ be adjointable operators on a Hilbert $C^{*}$ -module $E$ . Giving a suitable version of the celebrated Douglas theorem in the context of Hilbert $C^{*}$ -modu…
