WebProof. Since A is a symmetric tensor, it has got exactly three eigenvalues, Λ1, Λ 2, Λ 3, by Theorem 2.13.2. Let v1, v2 and v3 be the corresponding eigenvectors. Since Λ 1, Λ 2 and Λ 3 are not necessarily distinct, the following three cases arise. Case (i). Suppose Λ 1 Λ 2 and Λ 3 are all distinct. WebGame theory is the study of mathematical models of strategic interactions among rational agents.
