Consider the question whether it is true that a prime number $p$ divides $1^1+2^2+3^3+....+(p-1)^{p-1}$ if and only if $p \in \{17,19\}$.
For the obvious heuristic reasons, for large $n$ one would expect there to be roughly $\ln(\ln(n))$ such p... | {"url":"http://mathoverflow.net/questions/131973/distinctive-property-of-the-primes-17-and-19","timestamp":"2014-04-18T10:49:07Z","content_type":null,"content_length":"64622","record_id":"<urn:uuid:16cc03ef-244b-42df-9947-21d2f0bf351c>","cc-path":"CC-MAIN-2014-15/segments/1397609533308.11/warc/CC-MAIN-20140416005213-00... |

From Gerris
Functions can be used in most objects which require a numerical parameter. A function can be a constant or a piece of C code taking coordinates (x,y,z), time t or any of the domain variables as
arguments and returning a floating-point value.
The syntax in parameter files is as follows:
