On a class of hexagonal-web of spheres

Hakki Ismail Erdogan, Kadir Has University, Istanbul

 

In this work, we consider four one-parameter families of spheres which do not belong to the same bundle with the additional condition that the three families of spheres cut the spheres of the fourth familiy in a hexagonal three-web formed by the three families of curves defined by the equations

$ x^2+y^2+a^2+u_{1}x=0,~~~~~ y-u_{2}x=0,~~~~~ x^2+y^2-{u_3}=0,~~~~~ (a\in R, a\ne 0)$.

Then, we determine these four families of spheres so that form a surface 6-web.
