  Special functions have always played a central role in physics and in
mathematics, arising as solutions of particular differential equations, or
integrals, during the study of particular important physical models and
theories in Quantum Mechanics, Thermodynamics, Fluid Dynamics, Viscoelasticity,
et cetera. The aim of this short series of lectures is to provide a good
treatise about the Exponential Integral special function, covering also a few
selected topics like its generalisation, other related special functions (Sine
Integral, Cosine Integral and the Logarithmic Integral) and the theory of
Asymptotic Series.
