A $$C^0$$-theory for the blow-up of second order elliptic equations of critical Sobolev growth. (English) Zbl 1061.58020
Summary: Let $$(M,g)$$ be a smooth compact Riemannian manifold of dimension $$n \geq 3$$, and $$\Delta_g = -div_g\nabla$$ the Laplace-Beltrami operator. Also let $$2^\star$$ be the critical Sobolev exponent for the embedding of the Sobolev space $$H_1^2(M)$$ into Lebesgue spaces, and $$h$$ a smooth function on $$M$$. Elliptic equations of critical Sobolev growth like $\Delta_gu + hu = u^{2^\star-1}$ have been the target of investigation for decades. A very nice $$H_1^2$$-theory for the asymptotic behaviour of solutions of such an equation is available since the 1980’s. In this announcement we present the $$C^0$$-theory we have recently developed. Such a theory provides sharp pointwise estimates for the asymptotic behaviour of solutions of the above equation.
