Question: Recall the 'emptiness testing' language E_TM = { |M is a TM and L(M) =}. Define a mapping reduction from E_TM (the complement of E_TM)

 Recall the 'emptiness testing' language E_TM = {|M is a TM

Recall the 'emptiness testing' language E_TM = {|M is a TM and L(M) =}. Define a mapping reduction from E_TM (the complement of E_TM) to the language B = { | Q is a TM such that 011 elementof L(Q)}. You can use the fact that E_TM is Turing recognizable and can assume there exists a recognizer R for E_TM in your construction (you don't have to describe how R works)
