\varPsi

The Greek letter \varPsi is used in mathematics and physics to represent various concepts, such as wave functions in quantum mechanics, stream functions in fluid dynamics, and sometimes as a variable in equations. It is the uppercase form of the Greek letter psi.

Examples

Ψ (x) = \int e^{- x^{2}} d x

Represents a wave function in quantum mechanics.

\varPsi(x) = \int e^{-x^2} \, dx

\nabla^{2} Ψ = 0

Used in fluid dynamics to represent a stream function in a potential flow.

\nabla^2 \varPsi = 0

Ψ = n = 1 \sum \infty \frac{1}{n ^{2}}

Represents a mathematical series or function.

\varPsi = \sum_{n=1}^{\infty} \frac{1}{n^2}
