A Note on the Convergence Along Tangential Curve Associated with Fractional Schrödinger Propagator and Boussinesq Operator
In this paper, the authors study the almost everywhere pointwise convergence problem along a class of restricted curves in given by {(y, t): y∈Γ(x, t)} for each t∈[0, 1], where Γ(x, t)={γ(x, t, θ): θ∈Θ} for a given compact set Θ in of the fractional Schrödinger propagator and Boussinesq operator. They focus on the relationship between the upper Minkowski dimension of Θ and the optimal s for which whenever .
