| Aug 5, 2011 at 16:07 | comment | added | Ioannis Souldatos | The left character of a point $x$ is the least cardinal $\kappa$ such that there is a cofinal sequence in the set $\{y|y<x\}$. The right character is defined symmetrically by considering coinitial sequences in $\{y|y>x\}$. The character of $x$ is the minimum of these two. | |
