Center node: "communicating concurrent functions"
  Abstract: In this article we extend the framework of execution of concurrent functions on different abstract levels from previous work with communication between the concurrent functions. We classify the communications and identify problems that can occur with these communications. We present solutions for the problems based on encapsulation and abstraction to obtain correct behaviours. The result is that communication on a low level of abstraction in the form of shared memory and message passing is dealt with on an higher level of abstraction.

Connected through hyperedge HE-1 (induced by source paper "from functions to object orientation by abstraction"):
  with members:
    - "a process calculus with finitary comprehended terms"
    - "instruction sequence processing operators"
    - "on the expressiveness of single pass instruction sequences"
    - "indirect jumps improve instruction sequence performance"
    - "concurrent models for object execution"
    - "concurrent models for function execution"
    - "thread algebra for poly threading"
    - "on object orientation"
