%0 Journal Article %T Introduction to Mathematical Physics. Calculus of Variations and Boundary-value Problems %A V. M. Adamyan %A M. Ya. Sushko %J Physics %D 2013 %I arXiv %X This book considers posing and the methods of solving simple linear boundary-value problems in classical mathematical physics. The questions encompassed include: the fundamentals of calculus of variations; one-dimensional boundary-value problems in the oscillation and heat conduction theories, with a detailed analysis of the Sturm-Liouville boundary-value problem and substantiation of the Fourier method; sample solutions of the corresponding problems in two and three dimensions, with essential elements of the special function theory. The text is designed for Physics, Engineering, and Mathematics majors. %U http://arxiv.org/abs/1306.1675v3
