OVERVIEW
the course focuses on the fundamental knowledge and methodologies of algebra and geometry, with the scope of providing students with the fundamental theoretical/practical tools to understand in breadth and depth the various disciplines which will subsequently be studied in the Physics degree. The course combines the formalism of algebra with the more applied aspects of geometry. The students will become accustomed to using geometrical intuition with algebraic reasoning to solve problems and develop an elastic and polyvalent thinking. The proofs will enable the students to gain a mathematical rigour which will allow them to develop specific capabilities to solve problems.
Knowledge and understanding: the topics explored throughout the module are considered to be necessary for other modules, the knowledge gained will be used in various contexts throughout the degree.
AIMS AND CONTENT
LEARNING OUTCOMES
The course aims to provide the fundamental notions of the theory of vector spaces (real and complex) of finite dimension, of linear transformations and of analytic geometry in the plane and in space. The skills to be developed are: solving linear systems, searching for eigenvectors and eigenvalues, diagonalising real symmetric matrices and Hermitian matrices; solve simple analytic geometry problems
AIMS AND LEARNING OUTCOMES
Application skills: part the theoretical background taught will be necessary for the application of techniques within algebra and geometry. The students should be able to explain and prove the theorems and their consequences and be able to apply the techniques learnt to solve problems, being able to understand and compare the different types of mathematical proofs
PREREQUISITES
vectors and vector calculations
basic algebra rules
sets notation and operations
TEACHING METHODS
Mode of teaching: the lectures will be carried out facetoface, the theoretical topics will be taught, the proofs will be shown and simple consequences to be proven will be assigned, fundamental problems will be solved on the board and additional exercises will be assigned in preparation for the written exam.
SYLLABUS/CONTENT
Prerequisites which will be furthered: vectors and vector calculations
Matrices: definition and operations with matrices, properties (powers, zero divisors, nilpotent matrices, invertibility), determinant of a square matrix, methods for calculating the determinant, in particular Laplace's theorem and elementary operations. Rank of a matrix, properties, methods for calculating the rank (Kronecker's theorem).
Linear systems: resolution of systems of linear equations with the Gauss method, results about existence and quantity of solutions using the properties ofthe matrix associated to the linear system (Cramer, RouchéCapelli)
Vector spaces and subspaces, linear dependance and linear independence, fundamentals of vector spaces, in particular orthonormal vectors. Direct sum of subspaces.
Linear functions: definition, properties, kernel and image of a linear function, dimension theorem; matrix of a linear function with respect to a base of the domain and one of the codomain, relation between the properties of the matrix and the properties of the linear function. Isomorphism between the space of linear functions between two vector spaces and a space of matrices. Similitude of matrices and properties of similar matrices.
Eigenvalues and eigenvectors of an endomorphism. Diagonalization of a square matrix.
Geometry in the plane and in the threedimensional space: vectors and operations with vectors (sum, product, scalar product, vector product); lines and their equations in the plane and in the threedimensional space; position of a line with respect to another line or to a plane, position of a plane with respect to another plane; orthogonal projection of a point on a line or on a plane, of a line on a plane, and their symmetric. Distance of a point from a plane or from a line. Circles, spheres, cones, cylinders and their equations in the three dimensional space.

EXAMS
EXAM DESCRIPTION
the exam consistent in a 23 hour written exam which has a minimum passing grade of 16/30 which allows the progression onto the oral exam. The minimum passing grade is an average of 18/30 out of the written and oral examinations.
During the term the students can take two exams about the topics covered until that time which then replace the written exam. The passing requirements follow the same criteria of the written exam, a minimum average of 16/30 is required between the two exams. The use of the scientific calculator will be allowed, not the use of the graphical calculator.
ASSESSMENT METHODS
The student can pass two written exams during the course solving problems according the topics covered until the exam date.
The student can pass the written exam according the university schedule time
In each case the student has to discuss the theory of all the topics covered during the entire year at the oral exam.
FURTHER INFORMATION
Recommendation for the student : regularly attend the lectures, take notes, refer to the notes shared on aulaweb, rework through the notes, be aware of the ongoing learning by solving the proofs and exercises on your own, ask course mates for clarification if necessary, use the lecturer’s available hours to clarify any doubt.
Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Sergio Di Domizio (sergio.didomizio@unige.it), the Department’s disability liaison.
