New books on physics and related sciences

stability, convergence, and error estimation. Compact difference schemes of enhanced accuracy for solving differential equations with variable coefficients are investi-gated. The book presents methods for constructing balance approximations of various orders on triangular and quad-rangular finite volumes. Also covered are modern net-point techniques, the structural, spectral, and monotonicity properties of algebraic equations, and direct and iterative methods for effectively solving high-order sparse-matrix systems. The book evolved from the lecture course taught by the author at Novosibirsk State University for many years. For undergraduate and post-graduate students and specialists in computational and applied mathematics.
