Abstract Soft factorization has been shown to hold to sub-leading order in QED and to sub-sub-leading order in perturbative quantum gravity. with various loop and non-universal corrections that can be found. Here we show that all terms factorizing at tree level can be uniquely identified as boundary terms that exist already in the classical expressions for the electric current and str... https://countryscenesaddleryandpetsuppliers.shop/product-category/ventech-elite-sports-medicine-boot/
