Naturally the common people don't want war; neither in Russia, nor in England, nor in America, nor in Germany. That is understood. But after all, it is the leaders of the country who determine policy, and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is to tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in any country.

A quick note on integrable systems on orbifolds

The aim of this note is to present some relatively simple remarks and observations about integrable Hamiltonian and non-Hamiltonian dynamical systems on orbifolds.

Motivation and definition

Orbifolds appear very naturally in many situations, in particular in the reduction theory of symmetric dynamical systems. So it is natural to develop a theory of integrable systems . . . → Read More: A quick note on integrable systems on orbifolds
