ring of integers उदाहरण वाक्य
उदाहरण वाक्य
- Taking " R " = " Z " this construction tells us precisely that rings of integers of number fields are Dedekind domains.
- We obtain an element of the ring of integers in this way; this is a polynomial of degree four in with coefficients in the-adic integers.
- In the general case, by Dirichlet's unit theorem, the group of units in the ring of integers of " K " is infinite.
- And back, starting from an algebraic number field ( an extension of rational numbers ), its ring of integers can be extracted, which includes as its subring.
- The " maximal order " of an algebraic number field is its ring of integers, and the discriminant of the maximal order is the discriminant the field.
- However, even over the ring of integers, the module of rational numbers has an endomorphism ring that is a division ring, specifically the field of rational numbers.
- Thus, a number field has class number 1 if and only if its ring of integers is a principal ideal domain ( and thus a unique factorization domain ).
- A natural generalisation of the construction above is as follows : let F be a number field with ring of integers O and \ mathrm G an algebraic group over F.
- From the point of view of abstract algebra, congruence modulo n is a congruence relation on the ring of integers, and arithmetic modulo n occurs on the corresponding quotient ring.
- The greatest common divisor may be defined and exists, more generally, for multivariate polynomials over a field or the ring of integers, and also over a unique factorization domain.
