Let V be a vertex operator superalgebra and g=(12···k)be a k-cycle which is viewed as an automorphism of the tensor product vertex operator superalgebra V^(■k).In this paper,we construct an explicit isomorphism from A_(g)(V^(■k))to A(V)if k is odd and to Aσ(V)if k is even whereσis the canonical automorphism of V of order 2 determined by the superspace structure of *** recover previous results by Barron(2016)and Barron and Vander Werf(2014)that there is a one-to-one correspondence between irreducible g-twisted V^(■k)-modules and irreducible V-modules(***σ-twisted V-modules)when k is odd(***).This explicit isomorphism is expected to be useful in our further study on the Zhu algebra of the fixed point subalgebra.

Constituting 6.5%to 19.6%of all stroke cases worldwide,non-traumatic intracerebral hemorrhage(ICH)represents the most devastating form of stroke,with aging,male gender,and hypertension being important risk factors that predispose individuals to ICH[1,2].Injuries following episodes of ICH can be classified into two forms,namely(1)primary injury arising from mechanical pressure exerted by the hematoma on adjacent tissues,(2)secondary injury resulting from oxidative stress and inflammation mediated by blood cell degradation products and coagulation factors[3].

Dear Editor,This letter addresses the formation control problem for constrained underactuated autonomous underwater vehicles (AUVs). The feasibility condition of the virtual control law is eliminated by introducing a nonlinear state dependence function (NSDF) that transforms the state of each AUV in the formation.
