This monograph presents an intuitive theory of trial wave functions for strongly interacting fermions in fractional quantum Hall states. The correlation functions for the proposed fermion interactions follow a novel algebraic approach that harnesses the classical theory of invariants and semi-invariants of binary forms.

This new edition includes the latest developments in the treatment of strongly interacting two-dimensional electrons and discusses the generalization from small to larger systems.The book provides explanations in a class-tested tutorial style, and each chapter includes problems reviewing key concepts and calculations.

Why read this book on Environmental Stress Screening ???If you are working in the electronic manufacturing industry and you have heard the questions :"Why did it fail in the field and not in the factory ?"The answer to this question is there was not a proper ESS program developed for this product. A good ESS program is develop from the ground up and the fallout data is tracked. The fallout data is used to alter the present ESS program. This new /altered program is tailored to the hardware and usually is less costly and should improve the product reliability."Why can't we use the same ESS program as the other guy ?"The answer to this is you can, if you are manufacturing the exact same product. If this is the case, you must be working with the other guy. A different product requires a different ESS program.OrIf you are working in the electronic manufacturing industry and you have heard the statements :"I won't do ESS, it's going to cost too much."Can you put a price on field returns or lost contracts because of poor quality ?"I don't need to ESS, I'll just be more careful during manufacturing."You can be as careful as you want. If you don't weed out the Latent defects the time bomb is ticking.Or (worst case condition)If you are working in the electronic manufacturing industry and you have heard the front door being locked for the last time because of poor Quality hardware being shipped to the customer: Unfortunately if this happens it is too late to do anything. Hopefully you will develop a strong ESS program that is cost effective, apply dynamic management of the ESS program by analyzing the fallout data and last but not least - use common sense.

Many scholars of sub-Saharan Africa agree that inward-oriented development policies have hampered economic development in the region.

This treatment of Solid State Physics offers modern coverage of the theory and related experiments. Integrated throughout are developments from the newest semiconductor devices. The book is structured to accommodate a two-semester course.
