The doctorate council is made up of 25 Professors of the University of L’Aquila.
The coordinator is Prof. Davide Gabrielli, the vice-coordinator is Prof. Debora Amadori
The program aims at training students to get a deep knowledge of the theoretical features of a mathematical subject
and to develop a qualified preparation to apply mathematical models in a diversified range of scientific areas.
The doctorate is one of the programmes of the INdAM-DP-COFUND-2015

Title: Variational derivation of continuum mechanics equationsProfessor: Francesco dell’Isola and/or Luca Placidi
Aim: The aim of this short course is to introduce the students to the variational methods that are used in continuum mechanics. Static and dynamic cases will be analyzed. The mathematical derivations will be done on the basis of assumptions that are formulated on the form of the action functional. In the static case, the action is reduced to the total energy functional and a method to derive its form from a discrete model is also sketched.
Duration: 10 hours divided into 5 lectures
Topics: The subjects developed during the course will be a suitable selection of the following ones: 3D continuum elasto-dynamic model derivations for the standard and for the strain gradient case. Euler-Bernoulli beam theory derived from an Action principle as well as from a discrete model. Continuum equations for materials with band gap for the 3D and for the 1D cases. The choice may depend on the interests of the students
MODELS: Standard and strain gradient elastic materials. Euler beams. Materials with band gap.METHODS: Variational methods. Heuristic homogenization procedure.
Program: A possible effective program may be the following:
LECTURE 1: It is shown in details the case of 3D continuum elasto-dynamic case for the standard.
LECTURE 2: It is shown in details the case of 3D continuum elasto-dynamic case for the strain gradient case.
LECTURE 3: Standard Euler-Bernoulli beam theory will be derived from an action.
LECTURE 4: Standard Euler-Bernoulli beam theory will be derived from a discrete model.
LECTURE 5: The derivation of the continuum equations for materials with band gap for the 3D and for the 1D cases will be shown.

Differential forms and application in geometry and physics
At a first glance, differential forms (also known as co-vectors) might seem as just a technical tool. Locally, 1-dimensional differential forms look just as the dual of vectors, which everybody is familiar with. However, differential forms capture some very deep global geometric- and topologic properties of the space they are attached to. Therefore, differential forms led to the discovery of a vast number of new results in area such as differntial-, symplectic-, contact- and algebraic geometry, algebraic topology, classical- and quantum mechanics, just to name a few. The course will be an introduction into differential forms.
Prerequisites: We will assume knowledge only in calculus in Rn (differentiation and integration). However, it would also be desirable, but not compulsory, some basic knowledge in: smooth manifolds, algebraic topology and differential geometry of surfaces.
