Abstract (EN):
Let tau be a strongly regular graph with three distinct eigenvalues. We obtain upper bounds lower than one for some of the generalized Krein parameters of tau using properties of the Kronecker and of the Hadamard product and working in the real Euclidean Jordan algebra spanned by 1 and A, where A is the adjacency matrix of tau.
