# What is annihilator ideal?

## What is annihilator ideal?

In mathematics, the annihilator of a subset S of a module over a ring is the ideal formed by the elements of the ring that give always zero when multiplied by an element of S.

### What is a faithful module?

Faithful. A faithful module M is one where the action of each r ≠ 0 in R on M is nontrivial (i.e. r ⋅ x ≠ 0 for some x in M). Equivalently, the annihilator of M is the zero ideal.

What does annihilator mean?

: a person or thing that entirely destroys a place, a group, an enemy, etc. : one that annihilates something or someone This would subsequently interrupt the relationship between man and nature, and change the original role of man upon the Earth from the guardian of nature to the biggest annihilator of nature. —

What is annihilator in linear algebra?

Annihilator (linear algebra), the annihilator of a subset of a vector subspace. Annihilator method, a type of differential operator, used in a particular method for solving differential equations.

## What does annihilate mean in math?

Mathematics. the set of all linear functionals that map to zero all elements of a given subset of a vector space.

### What is an ideal in algebra?

ideal, in modern algebra, a subring of a mathematical ring with certain absorption properties. The concept of an ideal was first defined and developed by German mathematician Richard Dedekind in 1871. In particular, he used ideals to translate ordinary properties of arithmetic into properties of sets.

What is module in teaching?

In education, the term “module” refers to an instructional unit that focuses on a particular topic.

What is a free Z module?

In mathematics, a free module is a module that has a basis – that is, a generating set consisting of linearly independent elements. Every vector space is a free module, but, if the ring of the coefficients is not a division ring (not a field in the commutative case), then there exist non-free modules.

## Is Annihilator a real word?

This shows grade level based on the word’s complexity. a person or thing that annihilates.

### What is an annihilator at Dutch Brothers?

The Annihilator® Cold Brew Breve (half and half) combines our smooth Cold Brew with chocolate macadamia nut syrup and half and half for a fun, bold flavor. Available iced or toasted (hot)!

Is the annihilator a subspace?

First note that for S ⊆ V, the annihilator ann(S) ⊆ V ∗ is a subspace of the dual space. 3. Also note for S ⊆ V, if W = Span(S) then ann(S) = ann(W).
