The threshold for perturbations depending only on the radius r in the cylindrical coordinate system and strong boundary conditions is studied. A new type of orientational transition caused by pure flexoelectric effect is found.8 pages, 3 figures. To appear in Mol. Cryst. Liq. Cryst. (2001)Soft Condensed MatterMaterials Sciencetext
