#### Resonant singular boundary value problems

(Rocky Mountain Mathematics Consortium, 1995-12-01)

Existence theory is developed for the ''resonant'' singular problem (1/(pq))(py')' + lambda(0)y = f(t,y,py') almost everywhere on [0, 1] with lim(t-->0+) p(t)y'(t) = ay(1) + blim(t-->1-) p(t)y'(t) = 0. Here lambda(0) ...

#### Existence theory for nonresonant singular boundary value problems

(Cambridge University Press (CUP), 1995-10-01)

We present some existence results for the ''nonresonant'' singular boundary value problem 1/pq(py')'+ mu y = f(t, y) a.e. on [0,1] with lim(t-->0) + p(t)y'(t)=y(1)=0. Here mu is such that 1/pq(pu')'+mu u=0 a.e. on [0,1] ...

#### Boundary value problems singular in the solution variable with nonlinear boundary data

(Cambridge University Press (CUP), 1996-10-01)

Existence results are established for the equation y '' +f(t, y) = 0, 0 < t < 1. Here f may be singular in y and f is allowed to change sign. Our boundary data include y(0) = y'(1) + ky(1) = 0, k > -1 and y(0) = ...
