We calculate the following quantities in the asymptotic limit of long times: 1) The average interval length (i.e., \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\;\\left\\langle l \\right\\rangle = \\sqrt {\\pi Dt}$$\\end{document} , 2) the time-independent probability density for the reduced length \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\sigma = 1/\\left\\langle l \\right\\rangle$$\\end{document} , and 3) the expected value of dl/dt for a given l, which is positive for and negative for \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$l > {l_c} = \\sqrt {2/\\pi } \\left\\langle l \\right\\rangle$$\\end{document} and negative for l < lc. The model is similar to one proposed by Louat for grain growth. Although it is not a good representation of the details of most physical processes of coarsening, it is of theoretical interest since it is one of the few cases for which analytic results can be obtained.""" ; ns1:editor ( [ a ns1:Person ; ns1:familyName "Gurtin" ; ns1:givenName "Morton E." ] [ a ns1:Person ; ns1:familyName "McFadden" ; ns1:givenName "Geoffrey B." ] ) ; ns1:genre "chapter" ; ns1:inLanguage "en" ; ns1:isAccessibleForFree false ; ns1:isPartOf [ a ns1:Book ; ns1:isbn "978-1-4613-9211-8", "978-1-4613-9213-2" ; ns1:name "On the Evolution of Phase Boundaries" ] ; ns1:keywords "Louat", "adjacent intervals", "analytic results", "asymptotic limit", "average interval length", "better representation", "boundary points", "cases", "coarsening", "coefficient", "common diffusion coefficient", "dL/dt", "density", "detail", "diffusion coefficient", "dimensional model", "dimensional stochastic model", "dt", "grain growth", "growth", "independent random walks", "interest", "interval length", "intervals", "length", "limit", "lines", "long time", "model", "most physical processes", "physical processes", "point", "probability density", "process", "quantity", "random walk", "representation", "results", "single point", "stochastic model", "theoretical interest", "time", "values", "walk" ; ns1:name "A One Dimensional Stochastic Model of Coarsening" ; ns1:pagination "101-105" ; ns1:productId [ a ns1:PropertyValue ; ns1:name "doi" ; ns1:value "10.1007/978-1-4613-9211-8_7" ], [ a ns1:PropertyValue ; ns1:name "dimensions_id" ; ns1:value "pub.1016403566" ] ; ns1:publisher [ a ns1:Organisation ; ns1:name "Springer Nature" ] ; ns1:sameAs , ; ns1:sdDatePublished "2022-05-20T07:47" ; ns1:sdLicense "https://scigraph.springernature.com/explorer/license/" ; ns1:sdPublisher [ a ns1:Organization ; ns1:name "Springer Nature - SN SciGraph project" ] ; ns1:url "https://doi.org/10.1007/978-1-4613-9211-8_7" ; ns2:license ; ns2:sdDataset "chapters" . a ns1:DefinedTerm ; ns1:inDefinedTermSet ; ns1:name "Mathematical Sciences" . a ns1:DefinedTerm ; ns1:inDefinedTermSet ; ns1:name "Statistics" . a ns1:Person ; ns1:affiliation ; ns1:familyName "Mullins" ; ns1:givenName "W.
