A MATHEMATICIAN from the University of the Philippines Diliman (UPD) and his Norwegian colleague have developed a new ...

An annihilator, in the context of differential equations, is a differential operator that, when applied to a given function, yields zero. More formally, if L is a differential operator and f(x) is a ...

ABSTRACT: The research paper investigates the computation of Casimir operators on s l 2 -modules associated with linear differential operators and symbols on the real line. The study considers spaces ...

Given a linear ordinary differential operator containing several unknown constants and a number of its eigenvalues, the values of the unknown constants are estimated. A precise formulation is provided ...

ABSTRACT: In the author’s recent publications, a parametric system biorthogonal to the corresponding segment of the exponential Fourier system was unusually effective. On its basis, it was discovered ...

The key is the word “differential” and understanding that investors, operators and advisors need different strengths. The best investors can almost see into the future. The best operators build ...

Abstract: In this article, we study a class of integro–differential equation systems with observations in the abstract setting of Hilbert spaces, which fit the second-order integro–differential ...

Abstract: The general receiving antenna is represented as a linear differential operator converting the incident field and its spatial derivatives at a single point in space to an output voltage. The ...

Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...
