{"product_id":"fractional-calculus-of-weyl-algebra-toshio-oshima-9784864970167","title":"Fractional Calculus of Weyl Algebra and Fuchsian Differential Equations","description":"In this book we give a unified interpretation of confluences, contiguity relations and Katz's middle convolutions for linear ordinary differential equations with polynomial coefficients and their generalization to partial differential equations. The integral representations and series expansions of their solutions are also within our interpretation. As an application to Fuchsian differential equations on the Riemann sphere, we construct a universal model of Fuchsian differential equations with a given spectral type, in particular, we construct a single ordinary differential equation without apparent singularities corresponding to any rigid local system on the Riemann sphere, whose existence was an open problem presented by N. Katz.Furthermore we obtain fundamental properties of the solutions of the rigid Fuchsian differential equations such as their connection coefficients and the necessary and sufficient condition for the irreducibility of their monodromy groups. We give many examples calculated by our fractional calculus.Published by World Scientific Education and distributed by World Scientific Publishing Co. for all markets\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Toshio Oshima\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 4864970165\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9784864970167\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Mathematical Society of Japan\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 11\/01\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 203\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback","brand":"Toshio Oshima","offers":[{"title":"Paperback","offer_id":48443279278335,"sku":"9784864970167","price":33.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_2ae1685e-5855-4132-9921-06ad55e8ebf6.jpg?v=1777204453","url":"https:\/\/www.whiterainbookhouse.com\/products\/fractional-calculus-of-weyl-algebra-toshio-oshima-9784864970167","provider":"WR Book House","version":"1.0","type":"link"}
