This textbook is devoted to second order linear partial differential equations. The focus is on variational formulations in Hilbert spaces. It contains elliptic equations, including some basic results on Fredholm alternative and spectral theory, some useful notes on functional analysis, a brief presentation of Sobolev spaces and their properties, saddle point problems, parabolic equations and hyperbolic equations. Many exercises are added, and the complete solution of all of them is included.
The work is mainly addressed to students in Mathematics, but also students in Engineering with a good mathematical background should be able to follow the theory presented here.

Alberto Valli is professor of Mathematical Analysis at the Department of Mathematics of the University of Trento. His research activity has concerned the analysis of partial differential equations in fluid dynamics and electromagnetism and of their numerical approximation by the finite element method. He also studied domain decomposition methods and their use in the discretization of partial differential equations. On these topics he wrote three books.
