One of the "Big Indie Books of Fall 2014"—Publishers Weekly "Ted Kooser must be the most accessible and enjoyable major poet in America. His lines are so clear and simple."—Michael Dirda,The Washington Post “Readers [of Splitting an Order] will find ‘characters’ both strange and wonderful, animal or human. There is a sense that time is passing quickly and that everything worthy must be captured and savored, from an old couple lovingly sharing a sandwich to another sowing seed potatoes to a tribute to an old dog who waits as age and winter approach… Master of the single-metaphor poem, Kooser offers images that evolve, fluid and unforced.”—Library Journal, starred review "Wisdom, compassion, and dignity continue to mark the poetry of Ted Kooser...Splitting an Order [is] a quiet collection that honors small victories and gives reasons to be hopeful."—Elizabeth Lund, The Christian Science Monitor "Kooser's ability to discover the smallest detail and render it remarkable is a rare gift."—Bloomsbury Review Pulitzer Prize winner and best selling poet Ted Kooser calls attention to the intimacies of life through commonplace objects and occurrences: an elderly couple sharing a sandwich is a study in transcendent love, while a tattered packet of spinach seeds calls forth innate human potential. This long-awaited collection from the former U.S. Poet Laureate—ten years in the making—is rich with quiet and profound magnificence. From "Splitting an Order": I like to watch an old man cutting a sandwich in half … and then to see him lift half onto the extra plate that he asked the server to bring, and then to wait, offering the plate to his wife while she slowly unrolls her napkin and places her spoon, her knife and her fork in their proper places, then smoothes the starched white napkin over her knees and meets his eyes and holds out both old hands to him. Ted Kooser is the author of numerous books of poetry and prose, including Delights and Shadows (Copper Canyon Press), which won the Pulitzer Prize. A former US Poet Laureate, Kooser serves as editor for "American Life in Poetry," a nationally syndicated weekly newspaper column.

Operator splitting (or the fractional steps method) is a very common tool to analyze nonlinear partial differential equations both numerically and analytically. By applying operator splitting to a complicated model one can often split it into simpler problems that can be analyzed separately. In this book one studies operator splitting for a family of nonlinear evolution equations, including hyperbolic conservation laws and degenerate convection-diffusion equations. Common for these equations is the prevalence of rough, or non-smooth, solutions, e.g., shocks. Rigorous analysis is presented, showing that both semi-discrete and fully discrete splitting methods converge. For conservation laws, sharp error estimates are provided and for convection-diffusion equations one discusses a priori and a posteriori correction of entropy errors introduced by the splitting. Numerical methods include finite difference and finite volume methods as well as front tracking. The theory is illustrated by numerous examples. There is a dedicated Web page that provides MATLABR codes for many of the examples. The book is suitable for graduate students and researchers in pure and applied mathematics, physics, and engineering.

Hindu and Greek mythologies teem with stories of women and men who are doubled. This text recounts and compares a range of these. The comparisons show that differences in gender are more significant than differences in culture.

Discover How Geometric Integrators Preserve the Main Qualitative Properties of Continuous Dynamical Systems A Concise Introduction to Geometric Numerical Integration presents the main themes, techniques, and applications of geometric integrators for researchers in mathematics, physics, astronomy, and chemistry who are already familiar with numerical tools for solving differential equations. It also offers a bridge from traditional training in the numerical analysis of differential equations to understanding recent, advanced research literature on numerical geometric integration. The book first examines high-order classical integration methods from the structure preservation point of view. It then illustrates how to construct high-order integrators via the composition of basic low-order methods and analyzes the idea of splitting. It next reviews symplectic integrators constructed directly from the theory of generating functions as well as the important category of variational integrators. The authors also explain the relationship between the preservation of the geometric properties of a numerical method and the observed favorable error propagation in long-time integration. The book concludes with an analysis of the applicability of splitting and composition methods to certain classes of partial differential equations, such as the Schrödinger equation and other evolution equations. The motivation of geometric numerical integration is not only to develop numerical methods with improved qualitative behavior but also to provide more accurate long-time integration results than those obtained by general-purpose algorithms. Accessible to researchers and post-graduate students from diverse backgrounds, this introductory book gets readers up to speed on the ideas, methods, and applications of this field. Readers can reproduce the figures and results given in the text using the MATLAB® programs and model files available online.
