I have recently become interested in idempotent semirings, but I haven't been able to find any good expository text on them. What are good resources for a graduate student to learn about idempotent semirings from an algebraic (rather than an applied) perspective? Textbooks or quality pdfs would suffice. Assume a solid background in graduate algebra in general but little previous exposure to idempotent semirings in particular.
Thanks!
Back when I was thinking about such things, I found these two resources valuable. They do study idempotent semirings and structures at length.
