We introduce a necessary and sufficient condition for the o-extensionality rule of higher-order equational logic to be conservative over first-order many-sorted equational logic for ground first-order equations. This gives a precise condition under which computation in the higher-order initial model
We present a very short proof of a conjecture of Richards and Liestman concerning set-to-set broadcasting. 0 1993 by John Wiley & Sons, Inc.
The aim of this paper is to show that for any n Β₯ N, n > 3, there exist a, b Β₯ N\* such that n=a+b, the ''lengths'' of a and b having the same parity (see the text for the definition of the ''length'' of a natural number). Also we will show that for any n Β₯ N, n > 2, n ] 5, 10, there exist a, b Β₯ N\
