What is the field [itex]Z_{2}[/itex]?
 
Physics news on Phys.org
I'm guessing it is just another way of writting [itex]F_2[/itex]. Which is the field with elements 0,1 under addition and multiplication [itex]\mod 2[/itex]. Usually, the notation [itex]Z_2[/itex] is used to represent the group {0,1} under addition mod 2.
 
Thanks.
