JOURNAL FREE ACCESSIn this paper we shall define certain loop groups which act on simply connected H-surfaces in space forms preserving conformality, and obtain a criterion for these group actions to be equivariant.View full abstractDownload PDF (615K) -

JOURNAL FREE ACCESSLet X be a codimension two nonsingular subvariety of a nonsingular quadric 2n of dimension n≥5. We classify such subvarieties when they are scrolls. We also classify them when the degree d≤10. Both results were known when n=4.View full abstractDownload PDF (2187K) -

JOURNAL FREE ACCESSIn this paper we consider Jørgensen's inequalities for classical Schottky groups of the real type. The infimum of Jørgensen's numbers for groups of types II, V and VII are 16, 4(1+√2)2 and 4(1+√2)2, respectively, each of which is the best possible for Jørgensen's inequality.View full abstractDownload PDF (1568K) -

JOURNAL FREE ACCESSWe use N. Tanaka's theory of normal Cartan connections associated with simple graded Lie algebras to study Cartan's equivalence problem of single third order ordinary differential equations under contact transformations. As a result we obtain the complete structure equation with two differential invariants, which is applied on general Legendre Grassmann bundles of three-dimensional contact manifolds.View full abstractDownload PDF (1389K) -
