Title: 3-fold symmetric 2-orthogonal polynomials
Abstract: The main aim of this talk is to give an introduction to 3-fold symmetric 2-orthogonal polynomials. We will start this talk with a brief overview of symmetric orthogonal polynomials and also looking at some examples related with classical orthogonal polynomials. After that, 3-fold symmetric 2-orthogonal polynomials will appear as a 2-orthogonality analogue of symmetric orthogonal polynomials and results and examples of 3-fold symmetric 2-orthogonal polynomials will also be seen as analogues of results and examples of symmetric orthogonal polynomials.
