Axial anomaly in the gradient flow exact renormalization group
Yuki Miyakawa
The gradient flow exact renormalization group (GFERG) is a formulation of the exact renormalization group that keeps exact gauge invariance. GFERG can keep also modified chiral inv…

Manifestly gauge invariant exact renormalization group for quantum electrodynamics
Yuki Miyakawa, Hidenori Sonoda, Hiroshi Suzuki
We formulate quantum electrodynamics on the basis of gauge (or BRST) covariant diffusion equations of fields. This is a particular example of the gradient flow exact renormalizatio…
