Hypothesis: HR 0: \(0 = 0\).
Conclusion: HR 136-k:
Surjective Cardinal Cancellation (depends on \(k\in\omega-\{0\}\)): For all cardinals \(x\) and \(y\), \(kx\le^* ky\) implies \(x\le^* y\).
List of models where hypothesis is true and the conclusion is false:

| \(\cal N20\) Truss' Model II | <p> Let \(X=\{a(i,k,l): i\in 2, k\in \Bbb Z, l\in\omega\}\), \(Y=\{a(i,j,k,l): i,j\in 2, k\in\Bbb Z, i\in\omega\}\) and \(A\) is the disjoint union of \(X\) and \(Y\) </p> |
