Complex function in r

WebA complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. Based on this definition, … WebNov 8, 2024 · In quantum mechanics, we work with the space $\mathcal{H} = L^2(\mathbb{R})$ of functions with complex value square integrable. Thus Hermitian operators will play a central role since they have a real mean, to which we can give a physical interpretation: $$\overline{\langle A\rangle} = \overline{\langle x Ax\rangle} = …

WebAlthough both conditions are notationally the same, the complex differentiability condition is actually much stronger than the differentiability condition for functions \(\mathbb{R} \to \mathbb{R}\). This is because as \(h\) approaches \(0\) in the complex limit, it must do so from all directions, of which there are infinitely many.
