In this paper, we consider a one-dimensional weakly degenerate wave equation
with a dynamic nonlocal boundary feedback of fractional type acting at a
degenerate point. First We show well-posedness by using the semigroup
theory. Next, we show that our system is not uniformly stable by spectral
analysis. Hence, we look for a polynomial decay rate for a smooth initial
data by using a result due Borichev and Tomilov which reduces the problem of
estimating the rate of energy decay to finding a growth bound for the
resolvent of the generator associated with the semigroup. This analysis
proves that the degeneracy affect the energy decay rates.
