Is it possible to solve the following differential equation analytically? y''(x) = A - B [exp(y(x)/C) - 1] where A, B and C are constants. Thank you...

can i submit same research work (multiple submission) in two different journal and conference? after getting the final result i will keep the work either in the journal or in the conference. i have submitted the work to a journal and the review result will take a long time. in the...

we know that the quantum well absorption coefficient is calculated by summing over the electron-heavy hole and electron-light hole transitions: α_{w}(E) = \sum_{n}α_{e_{n}-hh_{n}}(E) + \sum_{n}α_{e_{n}-lh_{n}}(E) where n is the n^{th} transistion. but when the photon flux is incident...

As far I am concern, similar research paper cannot be published in different conferences. But, a research paper already published in a conference “can also be published in a journal if it is worthy of it”. Is it true?? Sorry for my childish queries.

i have got a solution of my differential equation - consists of Bessel function and hyper-geometric function....should i call it as a closed form solution? and i would also like to know about the importance of closed form analytical solution of any problem...what is the greatness of...
