Nonconstructive Proof -- from Wolfram MathWorld

WebOct 15, 2024 · A proof is weakly constructive if it doesn't use LEM in any way. (But may use the decidability of a specific property for which this has been constructively proven). I think the counting argument is not strongly constructive because to define the summation I think you need to assume decidability of the propositions. http://math.ucla.edu/~pak/papers/recfin.pdf the game agony
