". . .an extraordinary text presenting, mathematically, delicate problems of numerical approximations in a very careful and yet accessible manner. "
---Mathematical Reviews
"...contains a lot of very useful material on the numerical analysis of the finite volume scheme.... ...useful to researchers and graduate students working on the numerical analysis of finite element methods and finite volume methods for elliptic problems."
---Zentralblatt fur Mathematik, 2000
"...an indispensable reference work for any numerical analyst who studies and uses finite difference, finite element, and finite volume methods and other approaches for solving partial differential equations and applications. Besides its value as an excellent reference book for the generalized difference methods or for some finite volume methods from the point of view of the generalized finite element method, many ideas, both in algorithm design and theoretical analysis, can be applied elsewhere."
