Laguerre Geometry of Surfaces in R 3

Acta Mathematica Sinica, English Series, 2005
Let f : M → R3 be an oriented surface with non–degenerate second fundamental form. We denote by H and K its mean curvature and Gauss curvature. Then the Laguerre volume of f, defined by L(f) = f (H2 – K)/KdM, is an invariant under the Laguerre transformations. The critical surfaces of the functional L are called Laguerre minimal surfaces.

Some Infinite Families of Locally Partial Geometries Generalizing the Classical Laguerre Planes

open access: yesEuropean Journal of Combinatorics, 1994
Starting with a subgeometry Ω embedded in a β-dimensional projective space PG(β, q), β ⩾ 1, we construct inductively a series of rank n residually connected geometries Γ(n, β, Ω), n ⩾ β, by putting Γ(β, β, Ω) = Ω and extending Γ(n - 1, β, Ω) with a ...
