摘要：We present a Wilson type operator obtained by adding terms in both the Laplacian as well as the first-derivative stencil, such that the resulting operator remains within a hypercube. Motivated by the effect this improvement has on the eigenvalue spectrum, we carry out a preliminary study of some important features of this operator, such as the approach to the continuum limit of several physical quantities. Throughout we compare to the standard Wilson operator.
