Difference Equations, Second Edition:
Difference equations, second edition, presents a practical introduction to this important field of solutions for engineering and the physical sciences. Topic coverage includes numerical analysis, numerical methods, differential equations, combinatorics and discrete modeling. A hallmark of this revision is the diverse application to many subfields of mathematics.* phase plane analysis for systems of two linear equations* use of equations of variation to approximate solutions* fundamental matrices and floquet theory for periodic systems* lasalle invariance theorem* additional applications: secant line method, bison problem, juvenile-adult population model, probability theory* appendix on the use of mathematica for analyzing difference equaitons* exponential generating functions* many new examples and exercises [via]
