Abstract
CARDENAS, FRANQUI. Simplified Morasses without Linear Limits. Rev.colomb.mat. [online]. 2011, vol.45, n.1, pp.31-35. ISSN 0034-7426.
If there is a strongly unfoldable cardinal then there is a forcing extension with a simplified (ω2,1)-morass and no simplified (ω1,1)-morass with linear limits.
Keywords : Morasses; Square Sequences; Unfoldable cardinals.
