Intermediate prerequisites for E-infinity theory (Further recommended reading in nonlinear dynamics and mathematical physics)

The paper presents an intermediate level prerequisite for understanding E-infinity theory as applied to particle physics. It is the sequel to an earlier elementary level prerequisite paper (El Naschie MS. Elementary prerequisite for E-infinity. Chaos, Solitons & Fractals 2006;30(3):579-605). The work ends with a somewhat detailed discussion of the role which a Lagrangian type formulation could play in E-infinity theory.
