Description
Book SynopsisConsists of thirty lectures on diverse topics, covering much of the mathematical landscape. This title helps reader learn numerous results that often belong to neither the standard undergraduate nor graduate curriculum and discover connections between classical and contemporary ideas in algebra, combinatorics, geometry, and topology.
