The authors study time-harmonic Maxwell's equations in the junction of two rectangular waveguides. They prove existence and uniqueness of the solution, except for a discrete set of values of the ...
In this paper we derive the explicit, closed-form, recursion-free formulae for the arbitrary-order Fréchet derivatives of the exponential and logarithmic functions in unital Banach algebras (complex ...
Testing several approaches for implied volatility modeling and forecasting. Design/methodology/approach – Comparative ...
Polynomial equations are a cornerstone of modern science, providing a mathematical basis for celestial mechanics, computer graphics, market growth predictions and much more. But although most high ...
