The Christoffel-Darboux kernels for orthogonal polynomials in several real variables are investigated within the context of the three term recurrence relation reformulated for this purpose. Examples of orthogonal polynomials on the unit circle and on the Bernoulli lemniscate are discussed.
Comments: The paper has been gotten stuck in the editorial board of a journal since May, 2022. In the meantime the results were presented at the conference FAATNA20>22 (Matera, Italy)
