Heat Equation and Potential Burgers Equation

In this work, we construct the general solution to the Heat Equation (HE) and to many tensor structures associated to the Heat Equation, such as Symmetries, Lagrangians, Poisson Brackets (PB) and Lagrange Brackets (LB), using newly devised techniques that may be applied to any linear equation (e.g., Schrödinger Equation in field theory, or the small-oscillations problem in mechanics). In particular, we improve (increase the rank of) a time-independent PB found recently [1] which defines a Hamiltonian Structure for the HE, and we construct an Action Principle for the HE. We also find a new structure, which we call a Metric Structure (MS), which may be used to define alternative anti-commutative “Hamiltonian” theories, in which the Metricor M-Hamiltonians have to be explicitly time-dependent. Finally, we map some of these results to the Potential Burgers Equation (PBE).
