abstract= "View-Centric Reasoning (VCR) replaces CSP's perfect observer
with multiple, possibly imperfect observers. To employ
view-centric reasoning within existing CSP models requires a
bookkeeping change. Specifically, VCR introduces parallel
events as a new primitive for constructing traces, and
distinguishes two types of event traces: histories and
views. Previously, we gave the operational semantics of VCR,
and demonstrated the utility of parallel event traces to
reason for the first time unambiguously about the meaning of
the Linda predicate operations rdp() and inp(). The choice
of using an operational semantics to describe VCR makes
direct comparison with CSP difficult; therefore, work is
ongoing to recast VCR denotationally, then link it with the
other CSP models within Hoare and He's Unifying Theories of
Programming. Initial efforts in this direction led to a
comparison of VCR with Lawrence's HCSP. In this paper, we
present some recent insights and abstractions - inspired by
modern quantum physics - that have emerged whilst
contemplating parallel event traces in light of the unifying
theories. These insights lead to a more natural expression
of VCR traces, in the sense that they more closely resemble
CSP traces, thus forming a basis for linking VCR and CSP."
