Graphs of operators as points in the Grassmann manifold

Esteban Andruchow, Lazaro Recht, Alejandro Varela

We study the set $Γ$ of graphs of closed, densely defined operators in a Hilbert space $H$ , regarded as a subset of the Grassmann manifold $P (H \times H)$ of orthogonal projections…

The Riemann sphere of a C*-algebra

Esteban Andruchow, Gustavo Corach, Lázaro Recht +1

Given the unital C $^{*}$ -algebra $A$ , the unitary orbit of the projector $p_{0} = (1000)$ in the C $^{*}$ -algebra $M_{2} (A)$ of $2 \times 2$ matrices with…

The C $^{*}$ -algebra of a composition reflection

Esteban Andruchow

We study the C $^{*}$ algebra generated by the composition operator $C_{a}$ acting on the Hardy space $H^{2}$ of the unit disk, given by $C_{a} f = f \circ φ_{a}$ , where $$ φ_a(z)=\frac{a-z}{1-\ba…

Conjugate points in the Grassmann manifold of a $C^{*}$ -algebra

Esteban Andruchow, Gabriel Larotonda, Lázaro Recht

Let $G r$ be a component of the Grassmann manifold of a $C^{*}$ -algebra, presented as the unitary orbit of a given orthogonal projection $G r = G r (P)$ . There are several natural connecti…

Symmetries and reflections from composition operators in the disk

Esteban Andruchow, Gustavo Corach, Lázaro Recht

We study the composition operators $C_{a}$ acting on the Hardy space $H^{2}$ of the unit disk, given by $C_{a} f = f \circ φ_{a}$ , where $φ_{a} (z) = \frac{a - z}{1 - a ˉ z},$ for $∣ a ∣ < 1$ . These…

Multilingual training for Software Engineering

Toufique Ahmed, Premkumar Devanbu

Well-trained machine-learning models, which leverage large amounts of open-source software data, have now become an interesting approach to automating many software engineering tas…
