Abstract: In Chapter 1 we consider the following system of semilinear elliptic equations:

LU = F(x, U) + T? + H(x),
U = 0,

where l = diag (L, L), T E 2, L is a 2nd order elliptic operator in the divergent form, H is a fixed vector-function in C?(?) x C?(?) and <P~ is a positive...

Abstract: In Chapter 1 we consider the following system of semilinear elliptic equations:

LU = F(x, U) + T? + H(x),
U = 0,

where l = diag (L, L), T E 2, L is a 2nd order elliptic operator in the divergent form, H is a fixed vector-function in C?(?) x C?(?) and <P~ is a positive eigenfunction of ?'1 the dual operator of L. Using the Monotonic Iteration Method and Degree Theory, we find a curve r that splits the plane into two disjoint unbounded domains E and N ( 2 = E U N U ) such that: ...
