| Abstract: | Given any c], a], d] xxxxxxxxR/M such that d] ≤ a] ≤ c], a] is locally noncuppable between c] and d] if d] < a] ≤ c] and a] ∨ b] < c] for any b] xxxxxxxxR/M such that d] ≤ b] < c]. It will be shown that given any nonzero c] xxxxxxxxR/M, there are a], d] xxxxxxxxR/M such that d] < a] ≤ c] and a] is locally noncuppable between c] and d]. |
