Sesquilinear version of numerical range and numerical radius

Sesquilinear version of numerical range and numerical radius

In this paper by using the notion of sesquilinear form we introduce a new class of numerical range and numerical radius in normed space 𝒱, also its various characterizations are given. We apply our results to get some inequalities.
