Metric connections in projective differential geometry [PDF]
We search for Riemannian metrics whose Levi-Civita connection belongs to a given projective class. Following Sinjukov and Mikes, we show that such metrics correspond precisely to suitably positive solutions of a certain projectively invariant finite-type

Benenti Tensors: A useful tool in Projective Differential Geometry [PDF]
Two metrics are said to be projectively equivalent if they share the same geodesics (viewed as unparametrized curves). The degree of mobility of a metric g is the dimension of the space of the metrics projectively equivalent to g. For any pair of metrics

Integrable systems in projective differential geometry [PDF]
Some of the most important classes of surfaces in projective 3-space are reviewed: these are isothermally asymptotic surfaces, projectively applicable surfaces, surfaces of Jonas, projectively minimal surfaces, etc.

Differential geometry of Hilbert schemes of curves in a projective space [PDF]
We describe the natural geometry of Hilbert schemes of curves in ℙ3and, in some cases, in ℙn, n ≥ 4.

Projective differential geometry of curved surfaces [PDF]
The theory of surfaces, as developed by the author in the preceding three memoirs, was based upon the assumption that the surface considered was referred to its asymptotic curves. The complete system of invariants and covariallts was set up on that hypothesis.

Differential geometry of complex projective plane conics [PDF]
In this paper we study properties of complex plane projective curves from a geometric point of view. We focus our attention on properties of conics. We find that Gauss curvature determines a conic up to a hermitian transformation preserving the Fubini-Study metric of the complex projective plane and we discuss some other geometric properties of the ...

Some Formulae Arising in Projective-Differential Geometry [PDF]
We set up a framework in which some projective-differential intuitive concepts can be very easily formalized. Then we prove some general formulas.

Differential Invariants of Conformal and Projective Surfaces [PDF]
We show that, for both the conformal and projective groups, all the differential invariants of a generic surface in three-dimensional space can be written as combinations of the invariant derivatives of a single differential invariant. The proof is based
