Geometric Langlands Conjecture Implementation

🎯 Project Overview

This project implements the Geometric Langlands Conjecture using Rust, WASM, and CUDA, providing a high-performance computational framework for exploring this profound mathematical correspondence.

🧮 Mathematical Background

• Automorphic forms on a reductive group G over a function field
• Galois representations (or more generally, l-adic sheaves)

This duality connects:

• Representation theory and harmonic analysis
• Algebraic geometry and number theory
• Mathematical physics and quantum field theory
