SUMMARY
Heat transfer in a two-dimensional vacuum field primarily occurs through radiation, as conduction is not applicable in a vacuum. The heat equation governing conduction is expressed as u_t = u_{xx} + u_{yy}. In the context of thermal radiation, energy transfer is quantified by the Stefan-Boltzmann law, represented by E = σΔT^4, where σ is the Stefan-Boltzmann constant. This discussion clarifies that in a vacuum, thermal energy moves solely through radiative mechanisms.
