Approximation theory of linear operators investigates the systematic approximation of functions by sequences of linear mappings acting on function spaces. Central to the field are families of positive ...
Approximation theory in variable exponent Lebesgue spaces explores how well functions can be approximated when the underlying integrability exponent varies pointwise. Unlike classical Láµ– spaces with a ...
This course teaches commonly used approximation methods in quantum mechanics. They include time-independent perturbation theory, time-dependent perturbation theory, tight binding method, variational ...
