11. The derivative of any constant function is zero. 12. For \ lambda > n + p, the space contains only constant functions . 13. This is the ABSOLUTELY standard definition of a constant function in all the literature. 14. One of the reasons why this computation is possible is because is a constant function . 15. Among endofunctions on one finds permutations of and constant functions associating to each a given. 16. The rule holds in that case because the derivative of a constant function is 0. 17. In sheaf theory terms, a constant sheaf has locally constant functions as its sections. 18. An expression is context-insensitive if and only if its character defines a constant function . 19. It says that the only functions killed by { \ rm d } are constant functions . 20. The only regular functions which may be defined properly on a projective variety are the constant functions .
