{ "item_title" : "An Elementary Course on the Continuum Theory for Nematic Liquid Crystals", "item_author" : [" Giovanni Barbero", "Luiz Roberto Evangelista "], "item_description" : "This book was written to enable physicists and engineers to learn, within a single course, some topics in variational calculus, theory of elasticity, molecular models, and surface properties of nematic materials. It prepares graduate students for studies that require a simple knowledge in the physics of nematic liquid crystals.With this consideration in mind, the authors have formulated the problems concerning the continuum theory of liquid crystals into a precise form. In working out the solutions, they have analyzed, systematically and naturally, the techniques and methods of variational calculus. Special attention is dedicated to the analysis of well-posed and ill-posed variational problems. The presence of sub-surface discontinuity in the nematic orientation is analyzed using different techniques. A full chapter is devoted to this aspect of the theory of elasticity of nematic media.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/81/023/224/9810232241_b.jpg", "price_data" : { "retail_price" : "87.00", "online_price" : "87.00", "our_price" : "87.00", "club_price" : "87.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
