Predicting L-Function Properties from Trace-Index Graphs using Graph Neural Networks

Can GNNs predict arithmetic properties of modular forms? We construct trace-index graphs from Fourier coefficient data and show ChebConv achieves R²=0.625 for L-function zero prediction on 46,347 newforms from the LMFDB.
