Volenec, V.; Kolar-Begović, Z.; Kolar-Šuper, R. Thébault’s pencil of circles in an isotropic plane. (English) Zbl 1217.51015 Sarajevo J. Math. 6(19), No. 2, 237-239 (2010). The authors consider a pencil of circles in an isotropic plane which corresponds to Thébault’s pencil of circles in the Euclidean plane. They show that Thébault’s pencil of circles and Griffiths’s pencil of circles coincide in the case of an isotropic plane.
