We prove existence of Yamabe metrics on singular manifolds with conical points and conical links of Einstein type that include orbifold structures. We deal with metrics of generic type and derive a counterpart of Aubin’s classical result. The singular nature of the metric determines a different condition on the dimension, compared to the regular case.

We derive asymptotic expansions on the Yamabe quotient by adding a proper and implicit lower-order correction to standard bubbles, whose contribution to the expansion of the quotient can be determined combining the decomposition of symmetric 2-tensor fields and Fourier analysis on the conical links. Some perspectives for other singular manifolds will be discussed. This is joint work with Mattia Freguglia and Francesco Malizia.
