Explored conformal mapping: transformations that preserve local angles. The exponential function e^z turns rectangular grids into polar patterns, while Möbius transformations map the upper half-plane to a unit disk. Fundamental for solving PDEs in physics & engineering.

Ever wonder how mathematicians transform complex shapes while preserving angles? Just coded up conformal mappings in Python!
22
23
These special functions (like w = e^z and w = z²) take grid patterns and warp them into circles, spirals, and curves - but angles between lines stay the same. It's not just pretty math; engineers use this to solve fluid flow problems and design airfoils.

Implemented conformal mapping visualizations in Python using complex analysis. Key findings:
32
33
• Functions analytic at z₀ with f'(z₀) ≠ 0 preserve angles locally
34
• Exponential mapping e^z converts horizontal strips to annular sectors
35
• Möbius transformations (az+b)/(cz+d) map upper half-plane to unit disk
36
• Numerical verification shows angle preservation to machine precision
37
38
Applications: 2D potential flow, electrostatics, Riemann mapping theorem. The Jacobian has rotation matrix form, confirming geometric interpretation.

[OC] Visualizing Conformal Mappings: How Complex Functions Preserve Angles While Warping Space
46

BODY:

I created an interactive exploration of conformal mapping in complex analysis using Python and NumPy. Here's what I learned:
49
50
**What is Conformal Mapping?**
51
52
A conformal mapping is a transformation of the complex plane that preserves angles between curves. If you have two lines intersecting at 45°, after the transformation they'll still intersect at 45° - even though the lines themselves might be curved into circles or spirals.
53
54
**The Math (ELI5 version):**
55
56
For a function w = f(z) to be conformal at a point z₀, two things must be true:
57
1. The function must be analytic (smooth in a complex sense) at z₀
58
2. The derivative f'(z₀) cannot be zero
59
60
The derivative's magnitude |f'(z₀)| tells you how much the mapping stretches or shrinks distances, but the key insight is that it stretches equally in all directions - that's why angles are preserved.
61
62
**Three Classic Examples I Visualized:**
63
64
1. **Exponential Mapping (w = e^z)**: Horizontal lines become circles, vertical lines become rays from the origin. It's like converting rectangular coordinates to polar coordinates, but in a continuous, smooth way.
65
66
2. **Square Mapping (w = z²)**: Doubles angles and squares distances. A grid gets warped into a curved mesh, but perpendicular lines stay perpendicular.
67
68
3. **Möbius Transformation (w = (z-i)/(z+i))**: This one's wild - it maps the entire upper half of the complex plane into a unit disk. The real axis wraps around to form the circle's boundary.
69
70
**Why This Matters:**
71
72
Conformal mappings are used in:
73
- **Fluid dynamics**: Solving flow around airfoils (Joukowsky transformation)
74
- **Electrostatics**: Finding electric fields in complex geometries
75
- **Cartography**: Map projections that preserve angles (Mercator projection)
76
- **Pure math**: The Riemann Mapping Theorem says any simply connected domain can be mapped to a unit disk
77
78
**Numerical Verification:**
79
80
I tested angle preservation numerically by computing angles between horizontal and vertical directions before and after transformation. The angles matched to within 10⁻⁹ radians - basically machine precision.

The code is self-contained with matplotlib visualizations showing grid transformations. The beauty of conformal mapping is that it connects pure mathematics with practical applications in physics and engineering.

🔬 Just explored one of the coolest concepts in mathematics: conformal mapping!
94
95
Imagine drawing a grid on a rubber sheet, then stretching and bending it - but with one special rule: angles between lines must stay the same. That's what conformal mappings do in the complex number plane.
96
97
I visualized three classic transformations: exponential functions that turn rectangles into spirals, squaring that warps grids, and Möbius transformations that bend entire half-planes into circles.

Used in: airplane wing design, map projections, and solving physics equations!

Conformal Mapping: Angle-Preserving Transformations in Complex Analysis
109
110
I recently implemented a computational exploration of conformal mappings using Python, demonstrating key concepts in complex analysis with practical applications in engineering and physics.
111
112
**Technical Overview:**
113
114
Conformal mappings are complex functions w = f(z) that preserve angles locally. For a mapping to be conformal at z₀:
115
• f must be analytic at z₀
116
• f'(z₀) ≠ 0
117
118
The Cauchy-Riemann equations ensure the Jacobian matrix has the form of a scaled rotation, confirming angle preservation.
119
120
**Implementations:**
121
122
1. Exponential mapping (w = e^z): Converts rectangular grids to polar patterns
123
2. Square mapping (w = z²): Doubles angles while preserving orthogonality
124
3. Möbius transformation: Maps upper half-plane to unit disk
125
126
**Real-World Applications:**
127
128
• Aerodynamics: Joukowsky transformation for airfoil design
129
• Electrostatics: Solving Laplace's equation in complex geometries
130
• Cartography: Angle-preserving map projections
131
• Riemann Mapping Theorem: Fundamental result in geometric function theory
132
133
**Methodology:**
134
135
Numerical verification confirms angle preservation to 10⁻⁹ radian precision. Grid visualization demonstrates geometric properties of analytic functions.
