Uniqueness Theorems and Ideal Structure for Leavitt Path Algebras
Mark Tomforde
We prove Leavitt path algebra versions of the two uniqueness theorems of graph C*-algebras. We use these uniqueness theorems to analyze the ideal structure of Leavitt path algebras…
Injective and projective Hilbert C*-modules, and C*-algebras of compact operators
Michael Frank, Vern I. Paulsen
We consider projectivity and injectivity of Hilbert C*-modules in the categories of Hilbert C*-(bi-)modules over a fixed C*-algebra of coefficients (and another fixed C*-algebra re…
Ultragraph C*-algebras via topological quivers
Takeshi Katsura, Paul S. Muhly, Aidan Sims +1
Given an ultragraph in the sense of Tomforde, we construct a topological quiver in the sense of Muhly and Tomforde in such a way that the universal C*-algebras associated to the tw…
Open partial isometries and positivity in operator spaces
David P. Blecher, Matthew Neal
We study positivity in C*-modules and operator spaces using open tripotents, and an ordered version of the `noncommutative Shilov boundary'. Because of their independent interest,…
Noncommutative function theory and unique extensions
David P. Blecher, Louis E. Labuschagne
We generalize to the setting of Arveson's maximal subdiagonal subalgebras of finite von Neumann algebras, the Szegö -distance estimate, and classical theorems of F. and M. Rie…
