Equivalence problems in projective differential geometry [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1984
Equivalence problems for abstract, and induced, projective structures are investigated. (i) The notion of induced projective structures on submanifolds of a projective space is rigorously defined. (ii) Equivalence problems for such structures are discussed; in particular, it is shown that nonplanar surfaces in R

Conformally invariant differential equations and projective geometry

open access: bronzeJournal of Functional Analysis, 1981
AbstractWe combine harmonic analysis on certain pseudo-Riemannian symmetric spaces with results on conformally invariant linear and non-linear differential equations. This gives in many cases part of the decomposition of certain representations of the conformal group of a manifold when restricted to the isometry group.

Stationary Veselov-Novikov equation and isothermally asymptotic surfaces in projective differential geometry [PDF]

open access: yes, 1998
It is demonstrated that the stationary Veselov-Novikov (VN) and the stationary modified Veselov-Novikov (mVN) equations describe one and the same class of surfaces in projective differential geometry: the so-called isothermally asymptotic surfaces ...

On the theory of curved surfaces, and canonical systems in projective differential geometry [PDF]

open access: bronze, 1915
In a series of five memoirs,t Wilezynski has developed a projective theory of curved surfaces, employing in his study a method which is peculiarly his own.

The Projective Differential Geometry of Systems of Linear Homogeneous Differential Equations of the First Order [PDF]

open access: bronze, 1928
The tedious calculations that occasionally occur in studying projective differential geometry by means of the invariants and covariants of a completely integrable system of linear homogeneous differential equations are admittedly an unpleasant feature of
