Hi community :P
Need some help with a differential Equation:
3/2y(x)+xy'(x)+y'''(x)=0
actually I'm looking for an asymptotic solution, when x -> infinity.
I made some research about that Eq. and here what i have found:
1 guy found an asymptotic sol. for a more general eq.:
Hershenov, J. Solutions of the differential equation y''' +axy'+by = 0. Stud. Appl. Math. 55 (1976), 301-314.
other guy found a solution of a more general eq:
Pfeiffer, G. W. Asymptotic solutions of y"'+q(x)y'+r(x)y=0. J. Differential Equations 11 (1972), 145-155.
but unfortunaly i can't find any of those articles.
and the last thing which i know:
the eq. y'''-4xy'-2y=0 is a generaliaed Airy's eq. whose solutions are well studied...but its not a thing I am looking for...
any advice is very appreciated.
and if some one could find one of those articles i'll appreciate that VERY MUCH!
Thx for your concideration.
PS: Sorry my bad english.
