The Polynomial Endomorphisms of Graph Algebras
Rune Johansen, Adam P. W. Sørensen, Wojciech Szymański
We investigate polynomial endomorphisms of graph -algebras and Leavitt path algebras. To this end, we define and analyze the coding graph corresponding to each such an endomor…
C*-stability of discrete groups
Søren Eilers, Tatiana Shulman, Adam P. W. Sørensen
A group may be considered -stable if almost representations of the group in a -algebra are always close to actual representations. We initiate a systematic study of which…
does not embed in
Nathan Brownlowe, Adam P W Sørensen
For a commutative ring with unit we investigate the embedding of tensor product algebras into the Leavitt algebra . We show that the tensor product $L_{2,\mathbb{Z}}\o…
Geometric classification of unital graph C*-algebras of real rank zero
Søren Eilers, Gunnar Restorff, Efren Ruiz +1
We generalize the classification result of Restorff on Cuntz-Krieger algebras to cover all unital graph C*-algebras with real rank zero, showing that Morita equivalence in this cas…
On a counterexample to a conjecture by Blackadar
Adam P. W. Sørensen
Blackadar conjectured that if we have a split short-exact sequence 0 -> I -> A -> A/I -> 0 where I is semiprojective and A/I is isomorphic to the complex numbers, then A must be se…
