The complex conjugate of z = Rei=a+bi is
z = Re = a - bi,
which is the reflection of z across the real axis.

Let D and D' be simply connected domains in C, and let f: DD' be a biholomorphic
(conformal) map.
1. Preservation of Laplace's Equation:
Show that if u : D'→R is a harmonic function on D', then u of is a harmonic function
on D.
2. Conformal Invariance of the Laplacian:
Prove that the Laplacian operator is conformally invariant up to a scaling factor. Specifically,
demonstrate that for f : DD' biholomorphic and u twice continuously differentiable.
A(f) = f(z)²(Au) of.
3. Dirichlet Problem and Conformal Mapping:
Consider the Dirichlet problem for a harmonic function on D' with boundary values given
by a continuous function : OD'→R. Use the conformal map f to transform this
problem to D and solve for the harmonic function on D.
4. Schwarz-Pick Lemma Extension:
⚫Extend the Schwarz-Pick Lemma to bounded symmetric domains and discuss its
implications for the hyperbolic metric under biholomorphic mappings.
5. Applications to Fluid Dynamics:
Apply the results from parts 1-3 to model potential flow around a simple obstacle.
Specifically, use a conformal map to transform the flow domain and solve for the velocity
potential and stream function.
