In this question, An Introduction to the Theory of Groups by Rotman is recommended twice as a good second-course group theory text. However, after reading the reviews here, and seeing this pdf of what seems to be corrections to Rotman, I am pretty concerned about the apparently many errors in the text. While some errors and their corrections may be pretty self-evident, I would hate to constantly be worrying about developing some misconception as a result of some fact that isn't presented quite as it should be.
To those who have read An Introduction to the Theory of Groups by Rotman: do you feel the errors are a serious concern/disruption to the flow of the text, or is the book still pretty navigable?
Also recommended in the question linked to above was A Course in the Theory of Groups by Robinson. I really like the look of this text, based on the table of contents and the group-theoretic concepts that really interest me.
The Robinson text is said (in the linked-to question) to 'move pretty quickly into deeper waters.' My background consists of basic group theory, ring theory, field theory, a little Galois theory, linear algebra, topology, real analysis, and graph theory (I have seen a decent amount of material and have been self-studying for a few years now).
Do you think that I can reasonably wade into these deeper waters without going in over my head and drowning? I realize this is a little subjective since no one knows my exact abilities, but I love group theory and am definitely willing to put some real effort into it.
Thanks in advance for the advice.
