DESCRIPTION:Title: Q-curvature\, Paneitz operator and a maximum principle\n
 	Abstract: In this talk\, I will discuss the higher-order version of the Ya
 mabe problem: 'Given a compact Riemannian manifold (M\,g)\, does there exi
 st a metric conformal to g with constant Q-curvature'? The behaviour of Q-
 curvature under conformal changes of the metric is governed by certain con
 formally covariant powers of the Laplacian. The problem of prescribing the
  Q-curvature in a conformal class then amounts to solving a nonlinear elli
 ptic PDE involving the powers of Laplacian called the GJMS operator. In ge
 neral the explicit form of this GJMS operator is not explicitly known. Thi
 s together with a lack of maximum principle for polyharmonic operators mak
 es the problem challenging. In this talk\, I will mainly focus on the biha
 rmonic case and survey some recent developments.\n
