GEOMETRIZATION OF A GENERAL COLLINEATION
, 1992 Geometrization of a general collineation means to express the collineation as necessary and sufficient conditions on the kinematic quantities (shear, vorticity, expansion) of the congruence of the vector field generating the collineation.

On the fixed point of a collineation of the real projective plane
, 2007 Using the "extended Euclidean plane" model we prove the existence of the fixed point of a collineation of the real projective plane. At first we obtain the collineation as a product of a reflection in a line, a reflection in a point and a central-axial ...

Reply to Collins and Altman [PDF]
European Journal of Cardio-Thoracic Surgery, 2012 We are pleased that EuroSCORE II [1] continues to generate interest and are happy to respond to concerns about its development and evaluation [2]. We find very little to disagree with in the points raised by Collins and Altman [3], but are not convinced that their suggested alternative analysis would have resulted in materially different results.

Collineation groups strongly irreducible on an oval in a projective plane of odd order
, 2015 Strongly irreducibile collineation groups have played an important role in the study of collineation groups of a finite projective plane. The theory of strongly irreducible collineation groups containing perspectivities is well developed, but not many ...

A Theorem on Harmonic Homologies [PDF]
, 1965 A collineation is a one-one mapping of a projective plane onto itself, taking points into points, lines into lines and preserving incidence, ([1], p. 247).

VISUAL FEEDBACK IN PROBLEMS OF MOVING OBJECTS CONTROL
Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2006 Possibility of using planar collineation parameters for forming control actions in visual control systems of moving objects is studied. Through examples of solving problems of attitude control, translation motion control and stabilization of screw ...
