In acid, Mn2+ and O2. In alkali, MnO2 and O2.
In alkali, you also get the catalytic disproportionation, on the surface of the MnO2, of hydrogen peroxide to water and oxygen, which can get quite violent as it warms up. Fun, but do take proper safety precautions.
This is one of the unusual reactions in which hydrogen peroxide acts as a reducing agent. It is also a little unusual in that the final oxidation state of the manganese, and therefore the overall ratio of oxidising to reducing agent, depends on the ph.
For many reactions of permanganate, it is usual to warm the solution of reducing agent. But not in this case, because you would simply decompose it.
