Solutions To Abstract Algebra Dummit And: Foote Better

If you are stuck on a specific, "star-rated" problem, Mathematics StackExchange is your best friend. By searching the specific problem number (e.g., "Dummit and Foote Section 12.1 Exercise 5"), you will almost certainly find a detailed discussion. The advantage here is the "why" behind the proof is often explained in the comments. 4. Slader / Quizlet (Formerly)

The official answer from most professors is "yes." The unofficial answer from most students who have passed their quals is "it depends."

But caution: the unofficial solutions are not infallible. The author of this feature once spent an entire weekend debugging a proof of the Fundamental Theorem of Finitely Generated Abelian Groups, only to discover that the "solution" from a popular online PDF had a subtle but fatal error in its handling of invariant factors.
