{"product_id":"gauge-theory-and-variational-principles-9780486445465","title":"Gauge Theory and Variational Principles","description":"This text provides a framework for describing and organizing the basic forces of nature and the interactions of subatomic particles. A detailed and self-contained mathematical account of gauge theory, it is geared toward beginning graduate students and advanced undergraduates in mathematics and physics. This well-organized treatment supplements its rigor with intuitive ideas.\u003cbr\u003eStarting with an examination of principal fiber bundles and connections, the text explores curvature; particle fields, Lagrangians, and gauge invariance; Lagrange's equation for particle fields; and the inhomogeneous field equation. Additional topics include free Dirac electron fields; interactions; calculus on frame bundle; and unification of gauge fields and gravitation. The text concludes with references, a selected bibliography, an index of notation, and a general index.\u003cbr\u003e","brand":"Dover Publications","offers":[{"title":"Default Title","offer_id":50527056953618,"sku":"9780486445465","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_95480b9d-db4b-4157-b58d-df0381dc7492.jpg?v=1731290832","url":"https:\/\/surprise-castle.myshopify.com\/products\/gauge-theory-and-variational-principles-9780486445465","provider":"Surprise Castle","version":"1.0","type":"link"}
