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?

hi
i am a math student and right now i am working on Bratu;s problem if u search Bratu;s problem in google and sciencedirect u can find a lot of articles about that. Bratu type equation is u''(x) + a*e^u(x)=0
 
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.
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
