We prove that, for and , the function is strictly concave on if and only if where represents the generalized complete p-elliptic integrals of the first kind defined by where , , and is the generalized sine function, with This extends the recently obtained corresponding result for the case that p = 2. We then apply this concavity property to obtain the following functional inequality (likewise extending the previously established result for the case that p = 2): For all , we have where , , and . Both bounds are sharp. The sign of equality holds if and only if .
