WebFeb 17, 2024 · This paper is concerned with the blow-up phenomenon for classical heat equation with a nonlocal weighted exponential boundary flux. Based on the method of super- and sub-solutions, Kaplan’s argument, the Bernoulli’s techniques and modified differential inequality, we analyze the influence of the weighted function and the nonlocal … 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…
