Description
In supergravity, the construction of viable models of inflation is challenging
due to the so-called $\eta$-problem, which states that the flatness of the
inflaton potential is typically spoiled by supergravity corrections. We
discuss strategies to overcome this problem and how they can be applied to
classes of inflationary models. In this context, we also propose a new class
of models, referred to as tribrid inflation, which is particularly suitable
for solving the $\eta$-problem using either a Heisenberg symmetry or a shift
symmetry of the Kaehler potential.
