why does in case of asking the slave always come a

even if you dig a A-record he is authoritative?
because you request recursion and the server does not provide it.
use "dig +norecurse" not to request recursion
i am asking a auth name server for it's own domain
where and why do i request recursion in that case?
dig can't read your mind and thus know what you want to emulate. For
most queries issued via dig, either a) the user wants to emulate a stub
resolver, or b) the RD flag doesn't matter either way. That's why RD=1
is the default. The +norecurse flag -- setting RD=0 -- is one of the
ways you tell dig to emulate an iterative resolver when it composes its
query. An even better emulation includes setting a reasonable buffer
size via EDNS0, since most modern iterative resolvers do that too.
