Soit un operateur elliptique du second ordre a coefficients complexes sur un ouvert de ℝ N . On obtient des conditions necessaires et suffisantes sur les coefficients, pour que le semi-groupe qu'il definit, suivant les conditions au bord consideree

We study different notions of subsolutions for an abstract evolution equation du/dt+Au∋f where A is an m-accretive nonlinear operation in an ordered Banach space X with order-preserving resolvents. A first notion is related to the operator d/dt+A i

The invariance of a closed and convex set under a semigroupS(t)associated with a nonlinear form is investigated. Other properties of increase and domination of the semigroupS(t)are also derived. Examples are also given to demonstrate the power of the

LetA be a (nonlinear) operator in an ordered linear spaceX with resolvantJ λ=(I+λA)-1 well-defined onX and non-decreasing for any smallλ>0, andν ∈X. We define sub-potential ofν with respect toA, as anyu ∈X satisfyingu≧J λ(u+λv) for small
