摘要:
For a particle moves on a two-dimensional curved surface, we examine it in three-dimensional flat space rather than on the surface itself. Because no geometric surface of zero thickness exists in the realistic world, it is better to conceive of a surface as a limiting case of a curved shell of equal thickness d, where the limit d→0 is then taken. There is a noninterchangeability of computational order: firstly taking limit d→0 then defining the derivatives on the surface, and firstly taking derivatives in bulk then letting d→0. The latter procedure predicts the presence of the geometric momentum and geometric potential.
