A Tiling Approach to Chebyshev Polynomials


Chebyshev polynomials arise in a variety of continuous settings. They are a sequence of orthogonal polynomials appearing in approximation theory, numerical integration, and differential equations. In my theiss we approach them instead as discrete objects, counting the sum
of weighted tilings. Our combinatorial approach will allow us to prove identites holding for these continuous functions using discrete arguments.
