Blow-Up Analysis for Heat Equation with a Nonlocal Weighted …

For the flux density received from a remote unresolvable "point source", the measuring instrument, usually telescopic, though not able to resolve any detail of the source itself, must be able to optically resolve enough details of the sky around the point source, so as to record radiation coming from it only, uncontaminated by radiation from other sources. In this case, spectral flux density is the quantity that describes the rate at which energy transferred by electro… WebNonlocal Weighted Exponential Boundary Flux Wentao Huo and Zhong Bo Fang Abstract.
