Contents
As can be explained by a logistic model with harvesting, if you catch too much fish of a particular kind from the ocean, then this species would eventually become extinct. This change from sustainable to unsustainable harvesting can be seen as a prototypical example of bifurcation phenomena. In this lecture, we discuss a general theory of bifurcation in a functional-analytic setting as well as its geometric and analytic applications to

one-dimensional dynamical systems (e.g. the logistic model),
nonlinear Dirac equations on spin manifolds,
Einstein equations in general relativity,
second-order semilinear PDEs in the Euclidean space, and
the Yamabe problem in conformal geometry,

depending on the audience interest.
