This field investigates the relationships and bounds between various function norms, particularly through inequalities that characterise the smoothness and approximability of functions, as well as the ...

Consider the Helmholtz equation · α p + k²αp = 0 in a domain that contains a socalled hard scatterer. The scatterer is represented by the value α - ϵ, for 0 < ϵ ≪ 1, whereas α = 1 whenever the ...
