• An algebraic introduction to the Kauffman bracket skein algebra (Helen Wong, CMC)

    On Zoom

    The Kauffman bracket skein algebra was originally defined as a generalization of the Jones polynomial for knots and links on a surface and is one of the few quantum invariants where the connection to hyperbolic geometry is fairly well-established.  Explicating this connection to hyperbolic geometry requires an understanding of the non-commutative structure of the skein algebra, […]

  • The magic of the number three: three explanatory proofs in abstract algebra (Gizem Karaali, Pomona)

    On Zoom

    When first learning how to write mathematical proofs, it is often easier for students to work with statements using the universal quantifier. Results that single out special cases might initially come across as more puzzling or even mysterious. Explanatory proofs, in the sense of Steiner, transform what might initially seem mysterious or even magical into […]

  • Region colorings in knot theory (Sam Nelson, CMC)

    On Zoom

    In this talk we will survey recent developments in the use of ternary algebraic structures known as Niebrzydowski Tribrackets in defining invariants of knots, with some perhaps surprising applications.

  • Representing integers by multilinear polynomials (Lenny Fukshansky, CMC)

    On Zoom

    Given a homogeneous multilinear polynomial F(x) in n variables with integer coefficients, we obtain some sufficient conditions for it to represent all the integers. Further, we derive effective results, establishing bounds on the size of a solution x to the equation F(x) = b, where b is any integer. For a special class of polynomials […]
