摘要: Abstract: External equality and absolute equality
are defined model independently by Fu. It is interesting and
important to know whether these two equalities coincide or not. There
are some results in Fu's paper for this issue. It is relatively
easy to prove the coincidence if the summation operator is in the
language, otherwise it is harder. In fact Fu proposed it as an open
problem whether the two equalities coincide in some languages without
summation. In this paper, the proofs of the coincidence in finite
CCS and π calculus without summation are given.
