摘要: For a Kac-Moody Lie algebra we study pairs of real roots the sum of which is a real root. More precisely, we study in which way the existence of such pair of roots determines the existence of certain subroot system within the root system....

Our findings reveal that investors used two mechanisms for managing identity multiplicity inter-relationships: some investors managed identity multiplicity by overlaying two of their identities as one, a mechanism we refer to as shadowing; others managed their three identities by keeping them distinct ...

Numerically, we find that for generic 10-particle kinematics, the four roots ri of this polynomial are distinct. This means that, contrary to the previous cases, the Jacobian contains genuine branch cuts (meaning that they cannot be removed by any redefinition of z). The integration variable z...
