| Nov 26, 2013 at 15:31 | comment | added | Bryan261 | I'm sorry, can I formulate my question differently ?! sorry, because i need to have $ \mathrm{Hdg}_k ( X ) \oplus \mathrm{Hdg}_k ( Y ) \to \mathrm{Hdg}_k ( X \bigcup Y ) $ surjective. In other words : do we have $ \mathrm{Hdg}_k ( X \bigcap Y ) \to \mathrm{Hdg}_k ( X ) \oplus \mathrm{Hdg}_k ( Y ) \to \mathrm{Hdg}_k ( X \bigcup Y ) \to 0 $ a exact sequence ? Thanks a lot. | |
