Here is this week's advanced math problem of the week. We have several members who will check solutions, but we also welcome the community in general to step in. We also encourage finding different methods to the solution. If one has been found, see if there is another way. Occasionally there will be prizes for extraordinary or clever methods.(adsbygoogle = window.adsbygoogle || []).push({});

Prove that if ##n > 0##, an even map between ##n##-spheres has even homological degree.
