{"product_id":"invariance-theory-hardback","title":"Invariance Theory - Hardback","description":"\u003cp\u003eThis book treats the Atiyah-Singer index theorem using the heat equation, which gives a local formula for the index of any elliptic complex. Heat equation methods are also used to discuss Lefschetz fixed point formulas, the Gauss-Bonnet theorem for a manifold with smooth boundary, and the geometrical theorem for a manifold with smooth boundary. The author uses invariance theory to identify the integrand of the index theorem for classical elliptic complexes with the invariants of the heat equation.\u003c\/p\u003e","brand":"Taylor \u0026 Francis","offers":[{"title":"Default Title","offer_id":45548961857774,"sku":"9780849378744","price":436.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/9612\/7726\/files\/9780849378744_70fd64b6-1820-461d-b0cf-da494f708540.jpg?v=1720269755","url":"https:\/\/bookland.com.au\/products\/invariance-theory-hardback","provider":"Book Land AU","version":"1.0","type":"link"}
