Differential geometry of grassmannians and the Plucker map
(VERSITAWARSAW, 2012)
Using the Plucker map between grassmannians, we study basic aspects of classic grassmannian geometries. For 'hyperbolic' grassmannian geometries, we prove some facts (for instance, that the Plucker map is a minimal isometric ...

Spinorial field and Lyra geometry
(Springer, 2006-10-01)
The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation laws, and get a scale relation relating ...

On the geometry of non-classical curves
(1992-03-01)
In this paper we relate the numerical invariants attached to a projective curve, called the order sequence of the curve, to the geometry of the varieties of tangent linear spaces to the curve and to the Gauss maps of the ...
