How does one prove a homomorphism between vector spaces?
To prove a homomorphism between vector spaces, one must show that the function preserves the operations of addition and scalar multiplication. This means that for any two vectors u and v in the domain, the function must satisfy f(u + v) = f(u) + f(v), and for any scalar c and vector u in the domain, the function must satisfy f(cu) = cf(u). Additionally, one must show that the function maps the zero vector in the domain to the zero vector in the codomain. By verifying these properties, one can prove that a function is a homomorphism between vector spaces.

How can I show that this is a group homomorphism?
To show that a function is a group homomorphism, you need to demonstrate that it preserves the group operation. In other words, for any two elements a and b in the domain group, the function applied to the product of a and b should be equal to the product of the function applied to a and the function applied to b. This property ensures that the function respects the group structure and is compatible with the group operation. You can prove this by directly applying the function to the group operation and showing that it satisfies the homomorphism property.

Are office supplies and stationery always on sale at the turn of the year?
Office supplies and stationery are often on sale at the turn of the year due to the end of the fiscal year for many businesses and the need to clear out old inventory.

What is the kernel of a ring homomorphism, where the elements of R that map to the zero element of S are r?
The kernel of a ring homomorphism is the set of elements in the ring R that map to the zero element in the ring S under the homomorphism. In other words, it is the set of elements r in R such that f(r) = 0, where f is the ring homomorphism. The kernel is an ideal of the ring R, and it is denoted by ker(f). The kernel plays an important role in the study of ring homomorphisms and is used to characterize properties of the homomorphism and the rings involved.
