book for study finite element method I want to study finite element method for study partial differential equations in particular for parabolic type equation. Can you recommend a book which includes espesially mathematical background?
Thanks in advance...
 A: I came up too late, but I recommend a series of books for finite element method with different approach for future reading.
For engineering approach:

*

*Huebner - The Finite Element Method For Engineers.
For a introduction to the mathematical theory:

*

*Sayas - A gentle Introduction to Finite Element Method  link.

*Brenner & Scott - The Mathematical Theory of Finite Element Method.

*Braess - Finite Elements Theory, Fast Solvers, and Applications in Elasticity Theory.

*Solin et al. - Higher-Order Finite Element Methods. (Implementation aspects)

Introductory books for research purposes.

*

*Demkowicz- Mathematical Theory of Finite Element Method link (For DPG method with optimal test functions).

*Gatica - A Simple Introduction to the Mixed Finite Element Method.

*Sayas - First steps in the boundary element method link

*Girault & Raviart - Finite element methods for Navier-Stokes equations.

*Monk - Finite Element Methods for Maxwell's Equations.
