GIFT Core

Formally verified mathematical relations from the GIFT framework. All theorems proven in Lean 4 and Coq.

Quick Start

pip install giftpy

from gift_core import *

print(SIN2_THETA_W)   # Fraction(3, 13)
print(GAMMA_GIFT)     # Fraction(511, 884)
print(TAU)            # Fraction(3472, 891)

Building Proofs

# Lean 4
cd Lean && lake build

# Coq
cd COQ && make
