Prove that every finite integral domain is a field. Give an
example of an integral domain which is not a field.
Please show all steps of the proof. Thank you!!
a. Give an example of a finitely generated module over
an integral domain which is not isomorphic to a direct sum of
cyclic modules.
b. Let R be an integral domain and let
M=<m_1,...,m_r> be a finitely generated module. Prove that
rank of M is less than or equal to r.
What is the difference between function and relation? Explain
by giving example.
Find the domain and range of these functions.
the function that assigns to each pair of positive integers the
first integer of the pair
b) the function that assigns to each positive integer its largest
decimal digit
c) the function that assigns to a bit
string the number of ones minus the number of zeros in the
string
d) the function that assigns to each
positive integer...
Let (Z, N, +, ·) be an ordered integral domain. Let {x1, x2, . .
. , xn} be a subset of Z. Prove there exists an i, 1 ≤ i ≤ n such
that xi ≥ xj for all 1 ≤ j ≤ n. Prove that Z is an infinite set.
(Remark: How do you tell if a set is infinite??)
