POSITIVE SOLUTIONS FOR SINGULAR BVPs ON THE POSITIVE HALF-LINE ARISING FROM EPIDEMIOLOGY AND COMBUST

In this work,we are concerned with the existence and multiplicity of positive solutions for singular boundary value problems on the half-line.Two problems from epidemiology and combustion theory set on the positive half-line are investigated.We use upper and lower solution techniques combined with fixed point index on cones in appropriate Banach spaces.The results complement recent ones in the literature.
