  • Our planet is nowadays continuously monitored by powerful remote sensors operating in wide portions of the electromagnetic spectrum. Our capability of acquiring detailed information on the environment has been revolutionized by revealing its inner structure, morphology and dynamical changes. The way we now observe and study the evolution of the Earth’s status has even radically influenced our perception and conception of the world we live in.

  • An equation is a statement of equality: Whatever is on the left-hand side of any equation is equal to whatever is on the right-hand side. The symbols in an algebraic equation usually cannot have arbitrary values if the equality is to hold. To solve an equation is to find the possible values of these symbols. The solution of the equation 5x − 10 = 20 is x = 6 because this is the only value of x for which this equation is a true statement. The algebraic procedures that can be used to solve an equation are all based on the principle that any operation...

  • A system of linear equations is called sparse if only a relatively small number of its matrix elements aij are nonzero. It is wasteful to use general methods of linear algebra on such problems, because most of the O(N 3 ) arithmetic operations devoted to solving the set of equations or inverting the matrix involve zero operands. Furthermore, you might wish to work problems so large as to tax your available memory space, and it is wasteful to reserve storage for unfruitful zero elements.

  • Finance is one of the fastest growing areas in the modern banking and corporate world. This, together with the sophistication of modern financial products, provides a rapidly growing impetus for new mathematical models and modern mathematical methods. Indeed, the area is an expanding source for novel and relevant "real-world" mathematics. In this book, the authors describe the modeling of financial derivative products from an applied mathematician's viewpoint, from modeling to analysis to elementary computation.

  • AFTER some fourteen years of teaching in American colleges and universities the author finds that the average high school graduate has not developed in himself a mathematical type of reasoning. lie therefore hopes that this treatment may in some measure accomplish this purpose. The first few chapters are devoted to a thorough review of high school algebra, for the author is convinced that most college freshmen need considerable drill on the fundamental processes of algebra before attempting a very extensive study of mathematics....

  • This is a textbook on geometric algebra with applications to physics and serves also as an introduction to geometric algebra intended for research workers in physics who are interested in the study of this modern artefact. As it is extremely useful for all branches of physical science and very important for the new frontiers of physics, physicists are very much getting interested in this modern mathematical formalism.

  • Sophisticated engines could not even happen until Maxwell’s use of dif- ferential equations in order to stop the engines of that time from flying apart, stopping, or oscillating wildly, so the mathematics here starts with advanced calculus. Today’s engines are far more sophisticated. Their designs require the solutions of complex non-linear partial differential equations and very advanced work with linear algebra. Today a major focus is on autonomous machines, machines that can do routine and even non-routine tasks without human control.
