Factorization à la Dirac Applied to Some Equations of Classical Physics
Mathematics, 2021 In this paper, we present an application of Dirac’s factorization method to three types of the partial differential equations, i.e., the wave equation, the scattering equation, and the telegrapher’s equation.

Direct Sampling for Recovering Sound Soft Scatterers from Point Source Measurements
Computation, 2021 In this paper, we consider the inverse problem of recovering a sound soft scatterer from the measured scattered field. The scattered field is assumed to be induced by a point source on a curve/surface that is known.

A method of factoring and the factorization of 𝐹₇ [PDF]
Mathematics of Computation, 1975 The continued fraction method for factoring integers, which was introduced by D. H. Lehmer and R. E. Powers, is discussed along with its computer implementation. The power of the method is demonstrated by the factorization of the seventh Fermat number
