Learning outcomes

The course presents an introduction to plane and space analytic geometry, in a projective, affine and metric environment, respectively. In particular, conics and quadrics are discussed in the different frameworks.
Both analytical (coordinates, matrices) and synthetic tools are employed. The ultimate aim is strengthening the student's
geometric intuition, abstraction, and computational expertise, in view of future developments and applications,
in different contexts.

LINEAR ALGEBRA AND ELEMENTS OF GEOMETRY (2nd module)
The course presents an introduction to plane and space analytic geometry, in a projective, affine and metric environment, respectively. In particular, conics and quadrics are discussed in the different frameworks.
Both analytical (coordinates, matrices) and synthetic tools are employed. The ultimate aim is strengthening the student's
geometric intuition, abstraction, and computational expertise, in view of future developments and applications,
in different contexts.
Review of geometric vectors, scalar and vector product. Affine spaces. Affine subspaces. Affine notions: incidence,
parallelism. Geometric interpretation of linear systems. Ordinary line, plane, space. Plane and space lines.
Pencils of lines and planes. Incidence, parallelism, coplanarity.
Barycentric coodinates.
Affine euclidean spaces. Distance between affine subspaces; examples.
The common perpendicular to skew lines. (Convex) angle between two lines, planes, a line and a plane.
The projective space associated to a finite dimensional vector space. Homogeneous coordinates. Projective
embedding (completion) of an affine space. The ordinary projective line, plane, space. Lines in projective plane.
Conics (elementary theory). Conics in projective plane and their classification. Tangent to a conic.
Polarity. Reciprocity theorem. geometric construction of polar lines. Self-polar triangles and geometric interpretation
of Sylvester's theorem. Pencils of conics. Affine classification of conics (deduced from incidence relations with
the line at infinity): ellipses, hyperbolas, parabolas. centre, diameters; conjugate diameters. Asymptotes.
Metric classification of conic; axes. Orthogonal invariants. Circles. Isotropic lines. Circular points. Foci. Directrices.
Comparison with the classical approach. Conics as Be'zier curves.
Quadrics and their projective, affine and metric classification.
Matrix approach to plane and spatial homographies.
Further topics in linear algebra: Sylverster's inertia theorem and the spectral theorem.
