Revisit of Maslov Type Index for Symplectic Paths,We recall that . is a symplectic space, and . is the symplectic group of .. That is . We denote by . the set of continuous and piecewise smooth symplectic paths starting from . and . the set of Lagrangian subspaces of .. We recall that .. We also denote by . the set of continuous and piecewise smooth symplectic paths.configuration 发表于 2025-3-28 23:57:21
