INTRODUCTION TO MATHEMATICAL PHYSICS
Learning outcomes of the course unit
The aim of the course is, on one hand, to provide wide supplements to subjects of Analytical Mechanics and, on the other, to tackle some problems connected with the classical equations commonly indicated as "Differential equations of Mathematical Physics" (potential equation, heat equation, wave equation, etc.)
