(③) Find the residue of the given function at every finite singular point: sinla 1 e...
The definitions for ordinary and regular singular point that we have given only apply if ro is finite. Sometimes it is necessary to look at the behaviour of the solution near infinity. This is 0 done by changing variables = 1/x and studying the resulting equation about a) Make this substitution into the following DE a(a)y" b(r)c(x)y = 0, independent variable Ç and rewrite it entirely in terms of the new b) What conditions do you require for to be...
An algebraic geometry a surface that is singular at every point.
