         A.Dirac chains and infinitesimal calculus 
            1. Tensor, symmetric and antisymmetric algebras
            2. Koszul complex 
            3. Dual pairs
        B. Topological vector spaces     
            1. Topological spaces and continuous functions (basics only)
            2. Banach spaces 
            3. Inductive and projective limits, compact linking maps 
            4. Dual and predual spaces, weak and strong topologies         
        C. Differential forms, currents and chains 
            1. Schwartz and tempered distributions, de Rham currents, Whitney’s sharp and flat chains, differential chains 
            2. Operator algebras   
        D. Basic measure theory 
            1. Hausdorff measure and dimension 
            2. Radon measures 
            3. Whitney isomorphism theorem 
II. Applications 
        A. Calculus of variations 
            1. Models of surfaces
                * Brief overview of historical models: Douglas’s immersed disks, Federer and Fleming’s integral currents (embedded and orientable submanifolds), rectifiable currents, Reifenberg's surfaces, Almgren’s varifolds, Harrison’s dipole surfaces 
                * Spanning sets defined using homology (Reifenberg, Almgren) vs cohomology (Harrison & Pugh), invariance properties
            2. Existence of surfaces spanning a prescribed curve minimizing elliptic functionals 
            3. Higher dimension and codimension     
        B. Further topics might include: lower semicontinuity of Hausdorff measure, Reynolds’ transport theorem, continuous coproduct on differential chains, predual to wedge product on forms, quantum field theory, fluid flows. Some of these additional topics are established results, some are works in progress, and some are dreams!
