Field of quotients of z i
Web(d)In the quotient ring Z[x]=(4,2x 1), we have the relations (I’ll sloppily omit the \bar" in the notation here) 4 = 0 and 2x 1 = 0, which together imply that 2 = 0, and hence (since 0 = 2x 1 = 0x 1 = 1) that 1 = 0, so 1 = 0. Thus the quotient ring is the zero ring, which means the ideal is the unit ideal, which is neither prime nor maximal. WebField of quotients Theorem A ring R with unity can be extended to a field if and only if it is an integral domain. If R is an integral domain, then there is a (smallest) field F containing R called the quotient field of R (or the field of quotients). Any element of F is of the form b−1a, where a,b∈ R. The field F is unique up to ...
