The question is in the title: from what I read in the answer to another question, Artin L-functions are conjecturally cuspidal automorphic L-functions for some algebraic group that can be transfered to $GL_{n}$. On the other hand, elements of the Selberg class are widely believed to be (cuspidal?) automorphic L-functions for $GL_{n}$. So where exactly lies the difference between those two sets of L-functions?
Thanks in advance.


Question: How can I get to view the North Face of the Eiger in Switzerland?
Answer: According to Google maps and sbb.ch, the most closer railroad station is Alpiglen:
. According sattelite map, you'll get beautiful view from there.  

Not sure where are you getting from to the Eiger, so you can search trains by youself.
If you have more specific information, please provide it.
