Presenting Dcpos and Dcpo Algebras
Dcpos can be presented by a preorder of generators and inequational relations expressed as covers. Algebraic operations on the generators (possibly with their results being ideals...

On the structure of generalized toric codes
Toric codes are obtained by evaluating rational functions of a nonsingular toric variety at the algebraic torus. One can extend toric codes to the so called generalized toric code...

Automata and Logics for Words and Trees over an Infinite Alphabet
In a data word or a data tree each position carries a label from a finite alphabet and a data value from some infinite domain. These models have been considered in the realm of sem...

Hybrid Branching-Time Logics
We introduce hybrid branching-time logics as extensions of CT L-like logics with hybrid machinery such as the downarrow-operator. Following recent work in the linear framework, we...
