JOINT DIAMONDS AND LAVER DIAMONDS [PDF]
The Journal of Symbolic Logic, 2019 Abstract The concept of jointness for guessing principles, specifically ${\diamondsuit _\kappa }$ and various Laver diamonds, is introduced. A family of guessing sequences is joint if the elements of any given sequence of targets may be simultaneously guessed by the members of the family. While equivalent in the case of
