1st Cycle Studies

Good knowledge of High School Mathematics.

Classes are expository and include examples to clarify and motivate abstract concepts, and exercises for applying the acquired knowledge. Substancial part of the time is devoted to problem-solving. Optional challenging problems are also proposed. During the semester, students may use tutorial time to clarify their difficulties and train their skills in problem solving.

The knowledge and the ability to prove results in elementary number theory and the capacity to apply them on problem solving. To develop a rigorous mathematical thinking.

The main competencies to be developed are: calculus ability; knowledge of mathematical results; generalization and abstraction; ability to formulate and solve problems; logical reasoning; rigorous and clear mathematical writing as well as oral communication; critical and independent thinking; research and independent learning; imagination and creativity.

The integer numbers. Well ordering and mathematical induction principles. Divisibility. Euclidean algorithm. Primes. Fundamental Theorem of Arithmetic. Congruences. Fermat’s Little theorem, Euler’s theorem, and Wilson’s theorem. Chinese remainder theorem. Lagrange’s theorem. Primitive roots. Arithmetic functions. Diophantine equations. Applications of number theory (for example, the basic version of the RSA encryption method).
