{"product_id":"distributions","title":"Distributions","description":"This book presents a simple and original theory of distributions, both real and vector, adapted to the study of partial differential equations. It deals with value distributions in a Neumann space, that is, in which any Cauchy suite converges, which encompasses the Banach and Fréchet spaces and the same “weak” spaces. Alongside the usual operations – derivation, product, variable change, variable separation, restriction, extension and regularization – Distributions presents a new operation: weighting.\u003cbr\u003e\u003cbr\u003eThis operation produces properties similar to those of convolution for distributions defined in any open space. Emphasis is placed on the extraction of convergent sub-sequences, the existence and study of primitives and the representation by gradient or by derivatives of continuous functions. Constructive methods are used to make these tools accessible to students and engineers.","brand":"ISTE Ltd and John Wiley \u0026 Sons Inc","offers":[{"title":"Default Product","offer_id":54217783116120,"sku":"9781786305251","price":137.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9781786305251__676ed5275ee40.jpg?v=1741157143","url":"https:\/\/agendabookshop.com\/products\/distributions","provider":"Agenda Bookshop","version":"1.0","type":"link"}
