Definition (Restricted symplectic and orthogonal groups)

The group of linear transformations g of an infinite dimensional symplectic vector space preserving the symplectic structure and also satisfying the condition

$$tr(A^{†}A)<\infty$$

on the operator

$$A=[J_g,J_0]$$

is called the restricted symplectic group and denoted $S{p}_{res}$ . The group of linear transformations g of an infinite dimensional inner-product space preserving the inner-product and satisfying the same condition as above on $[J_g,J_0]$ is called the restricted orthogonal group and denoted $S{O}_{res}$

机器草稿中的定义提及

定义（限制辛群与正交群）

无限维辛向量空间上保持辛结构并同时满足该条件的线性变换 $g$ 构成的群

$$tr(A^{†}A)<\infty$$

关于该算符

$$A=[J_g,J_0]$$

称为限制辛群，记作 $S{p}_{res}$。无限维内积空间上保持内积并满足与上述关于 $[J_g,J_0]$ 相同条件的线性变换 $g$ 构成的群称为限制正交群，记作 $S{O}_{res}$。
