1) reduction of operation
运算换算
3) bracket operator
换位运算符
4) noncommutative differential calculus
非交换微分运算
1.
Using noncommutative differential calculus,a difference complex is introduced on regular lattic and is proved to be exact by constructing homotopy maps,which is just a difference analogue of classical de Rham complex and Poincaré lemma.
运用非交换微分运算,在正规格点空间上给出差分复形的定义并构造同伦映射证明其正合性,这正是经典de Rham复形及Poincaré引理的差分离散形式。
5) commutability of dδ operations
dδ运算的交换性
