{"product_id":"9780486151878","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.","brand":"Dover Publications","offers":[{"title":"Default Title","offer_id":47106532966640,"sku":"9780486151878","price":12.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780486151878_p0.jpg?v=1763708435","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780486151878","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
