Main Question or Discussion Point

Hi all.
Can someone tell me what a bratu problem is?
I have just an equation on hand but I have no clue in what this equation is describing and how it is derived. Could anyone here refer me to some texts or websites about the bratu problem?

Bratu’s problem appears in combustion theory of fuel ignition. combustion
is rapid chemical reaction of two or more substances with a characteristic
liberation of heat and light. The burning of a fuel (e.g., wood, coal, oil, or
natural gas) in air is a familiar example of combustion. also bratu’s problem
has application in the Chandrasekhar model of the expansion of the universe
and nanotechnology.
