An Introduction to the Theory of Numbers by G. H. Hardy, E. M. Wright

M. Fontana, Appunti del corso TN1 (Argomenti della teoria classica dei numeri), http://www.mat.uniroma3.it/users/fontana/didattica/fontana_didattica.html#dispense

Type of delivery of the course

Lectures in class on blackboard and exercise classes. In the case of an extension of the health emergency from COVID-19, all the provisions that regulate the methods of carrying out the teaching activities and student assessment will be implemented. In particular, the following methods will apply: streaming lectures on the platform Microsoft Teams.

Type of evaluation

Written and oral exam. The written exam contains six non-theoretical exercises to be solved in two hours. Two tests during the semester can replace the written exam.
