| The paper investigated sets of indices of partial recursive functions and of recursively enumerable sets. |
| In modern terminology we say that the set of valid formulas of first-order logic is recursively enumerable. |
| On some systems the list can be set to recursively list files in subfolders. |
| We applied their equation to evaluate the recombination fraction for each generation recursively. |
| In the latter case, you must recursively delete subkeys before deleing the parent key. |
