imath

Represents a dotless lowercase i character commonly used in mathematical notation and complex number theory.

Overview

Primarily employed when mathematical expressions require a base letter i without the dot, especially useful when adding custom accents or when working with complex numbers.

Essential in physics and engineering for representing the imaginary unit without dot confusion
Often paired with \hat or other accents in quantum mechanics notation
Frequently used alongside \jmath for consistent mathematical typography
Provides cleaner appearance in equations where the dot might interfere with superscripts or diacritical marks

Examples

Using imath to represent the imaginary unit in complex analysis.

z = x + y\imath

z = x + y\imath

Defining a complex-valued function with explicit imath notation.

f(z) = e^{\imath\theta}

f(z) = e^{\imath\theta}

Writing a quantum mechanical state vector with imath.

|\psi\rangle = \frac{1}{\sqrt{2}}(1 + \imath)

|\psi\rangle = \frac{1}{\sqrt{2}}(1 + \imath)
