News & Announcements

XX/XX Notes to future self: My tentative schedule is wildly inaccurate. 

11/30 Final Exam time (for final presentations) is Wednesday, December 8th. 
      Instead of 8am, let's meet at 9am. Also, I reserved WA 103A since that room has 
      a nicer technology set up.

11/15 Homework #9 [Source: (.tex)] is due Monday, November 22nd.

      Instead of a Final Exam, we will have a final "project" of sorts. I would like everyone to
      select an algebra topic that either we didn't cover or we just lightly skimmed. Study your
      topic, create a handout (it should be at least one page front and back), and then you will
      give a 10-15 minute presentation about your topic during the final exam period...or earlier.
      The presentation could use slides (like tex slides or powerpoint) or just be a "chalk talk"
      like I generally do in class. My Fall 2020 MAT 2110 page has some sample slides.

      Past/suggested topics/ideas:
      Music Theory related to Group Theory
      Cryptography and Algebra
      Ordered Rings
      Cayley Graphs
      Series - The Jordan-Holder Theorem - Nilpotent Groups
      Solving the Cubic and Quartic Equations
      Geometric Constructability
      Lie Algebras
      Wedderburn's Theorem  
      Wedderburn's Little Theorem 
      Artin-Schreier Theorem
      Symmetric Functions
      Grobner Bases and other Computer Algebra stuff
      Algebraic Geometry - Like Hilbert's Nullstallensatz
      Transcedence Bases
      Pi and e are transcendental
      Differential Algebra
      Galois Theory
      Group Representations and Characters
      Tensor Products
      Special Types of Modules - Flat modules, Projective modules, Injective modules etc.
      Abstract Linear Algebra Topics - Like Dual Spaces, Infinite Dimensional Spaces,
                                       Cannonical Forms, etc.
