{"product_id":"9781907343582","title":"Nonlinear Dirac equation, magnetic monopoles and double space-time","description":"Beginnings of quantum mechanics are revised and the author starts from the point where relativity and quantum mechanics were compatible. A modified wave equation for the electron is used. The relativistic invariance is then enlarged to a greater invariance group and the first consequences are studied. This invariance applies to the whole electromagnetism, including magnetic monopoles. Another space-time variety is seen which is very different from the usual relativistic space-time.","brand":"Cambridge International Science Publishing","offers":[{"title":"Default Title","offer_id":47047069630704,"sku":"9781907343582","price":80.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781907343582_p0.jpg?v=1763618164","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781907343582","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
