We prove that each automorphism of finite order of the free Lie algebra of rank 3 over an algebraically closed field is conjugate
to a linear automorphism if the field characteristic fails to divide the automorphism order. 相似文献

Let■ be a compatible total order on the additive group Z~2,and L be the rank two HeisenbergVirasoro algebra.For any c=(c_1,c_2,c_3,c_4) ∈ C~4,we define a Z~2-graded Verma module M(c,■) for L.A necessary and sufficient condition for M(c,■) to be irreducible is provided.Moreover,the maximal Z~2-graded submodules of M(c,■) are characterized when M(c,■) is reducible. 相似文献

In this paper, we study the derivation Lie Algebra of the higher rank Virasoro-like algebra. We prove that it isomorphic to the skew derivation Lie Algebra. We also characterize the automorphism groups of the higher rank Virasoro-like algebra and the skew derivation Lie Algebra. This generalizes the result of some related references. 相似文献

Let F be a free Lie algebra of rank n ≥ 2 and A be a free abelian Lie algebra of rank m ≥ 2. We prove that the test rank of the abelian product F ×A is m. Morever we compute the test rank of the algebra F/gk( F) ¢F/\gamma _{k}\left( F\right) ^{^{\prime }}. 相似文献

for some point-block pair (P, l) are divided into 4 classes. 2 of these classes are formed by the Paley designs and the designs complementary to the Paley designs. For the other 2 classes restrictions on the parameters are obtained. In particular it is shown that the only such design having =1 is the projective plane of order 2.With 2 Figures 相似文献
