By George A. Anastassiou

This monograph provides univariate and multivariate classical analyses of complicated inequalities. This treatise is a fruits of the author's final 13 years of analysis paintings. The chapters are self-contained and a number of other complicated classes should be taught out of this e-book. vast history and motivations are given in each one bankruptcy with a finished record of references given on the finish. the subjects coated are wide-ranging and various. fresh advances on Ostrowski sort inequalities, Opial variety inequalities, Poincare and Sobolev sort inequalities, and Hardy-Opial kind inequalities are tested. Works on usual and distributional Taylor formulae with estimates for his or her remainders and functions in addition to Chebyshev-Gruss, Gruss and comparability of potential inequalities are studied. the implications offered are ordinarily optimum, that's the inequalities are sharp and attained. purposes in lots of parts of natural and utilized arithmetic, equivalent to mathematical research, chance, traditional and partial differential equations, numerical research, details idea, etc., are explored intimately, as such this monograph is acceptable for researchers and graduate scholars. will probably be an invaluable instructing fabric at seminars in addition to a useful reference resource in all technological know-how libraries.

Principles of Spread-Spectrum Communication Systems

Initially followed in army networks as a method of making sure safe communique while faced with the threats of jamming and interception, spread-spectrum structures are actually the center of industrial purposes corresponding to cellular mobile and satellite tv for pc conversation. This e-book offers a concise yet lucid clarification and derivation of the basics of spread-spectrum conversation structures.

This quantity is the final of 3 volumes dedicated to the paintings of 1 of the main widespread twentieth century mathematicians. all through his mathematical paintings, A. N. Kolmogorov (1903-1987) confirmed nice creativity and flexibility and his wide-ranging experiences in lots of varied components, resulted in the answer of conceptual and primary difficulties and the posing of latest, very important questions.
