A friendly introduction to low-dimensional topology: knots, surfaces, three-dimensional manifolds, the fundamental group, and point-set topology. Cultivate the intuitive ideas of continuity, convergence, and connectedness and get familiar with knot theory, the topology of surfaces and three-dimensional manifolds, and elementary homotopy theory.

**References:**Topology Now! by Robert Messer and Philip Straffin**Prerequisites:**Students enrolled in this project should have some exposure to the geometry of objects in higher-dimensional Euclidean spaces together with an appreciation of precise mathematical definitions and proofs. Courses in multivariable calculus and linear algebra plus a proof-oriented course would satisfy this prerequisite. A semester of abstract algebra is desirable.**Meetings:**Once per week from Sept 19, 2022 to Dec 15, 2022**Type:**Reading**Size:**1-3 students
