Jordan operator algebras: basic theory [PDF]
Jordan operator algebras are normâclosed spaces of operators on a Hilbert space which are closed under the Jordan product. The discovery of the present paper is that there exists a huge and tractable theory of possibly nonselfadjoint Jordan operator ...

The mathematical legacy of William Arveson [PDF]
This is a retrospective of some of William Arveson's many contributions to operator theory and operator algebras.

Semigroup homomorphisms on matrix algebras [PDF]
We explore the connection between ring homomorphisms and semigroup homomorphisms on matrix algebras over rings or $C^*$-algebras.

Boundary Representations for Operator Algebras [PDF]
All operator algebras have (not necessarily irreducible) boundary representations. A unital operator algebra has enough such boundary representations to generate its C*-envelope.

Fuglede-Putnam theorem for locally measurable operators [PDF]
We extend the Fuglede-Putnam theorem from the algebra $B(H)$ of all bounded operators on the Hilbert space $H$ to the algebra of all locally measurable operators affiliated with a von Neumann algebra.

Jordan maps and triple maps on algebras of unbounded operators [PDF]
The paper contains results on the structure of Jordan maps and several kinds of triple maps on standard algebras of unbounded operators in Hilbert spaces. These results are unbounded counterparts to results on algebras of bounded operators obtained by Lu, Moln\'ar and others ([3,4,6 -- 10]).

Similarity problems and length [PDF]
This is a survey of the author's recent results on the Kadison and Halmos similarity problems and the closely connected notion of ``length'' of an operator algebra.

Extension of positive maps [PDF]
We prove two extension theorems for positive maps from operator systems into matrix ...

The Calkin algebra has outer automorphisms [PDF]
Assuming the continuum hypothesis, we show that the Calkin algebra has 2^{aleph_1} outer automorphisms.

Quantum tori are limits of finite dimensional C*-algebras for the quantum Gromov-Hausdorff propinquity, a metric defined by the author as a strengthening of Rieffel's quantum Gromov-Hausdorff designed to retain the C*-algebraic structure.
