On various parameters of Zq-simplex codes for an even integer q
No full textIn this paper, we defined the Zq-linear codes and discussed its various parameters. We constructed Zq-Simplex code and
Zq-MacDonald code and found its parameters. We have given a lower and an upper bounds of its covering radius for q is an even integer.The first author would like to gratefully acknowledge the UGC-RGNF[Rajiv Gandhi National Fellowship], New Delhi for providing fellowship

No full textSearch for the Flavor-Changing Neutral-Current Decay t -> Zq in pp Collisions at s=1.96 TeV
No full textWe report a search for the flavor-changing neutral-current decay of the top quark t -> Zq (q=u, c) in pp= 4 jet final state candidate events, with and without an identified bottom quark jet, we obtain an upper limit of B(t -> Zq)< 3.7% at 95% C.L
Analysis on limit cycles of Zq-equivariant polynomial vector fields with degree 3 or 4
No full textAbstractThis paper presents a study on the limit cycles of Zq-equivariant polynomial vector fields with degree 3 or 4. Previous studies have shown that when q=2, cubic-order systems can have 12 small amplitude limit cycles. In this paper, particular attention is focused on the cases of q⩾3. It is shown that for cubic-order systems, when q=3 there exist 3 small limit cycles and 1 big limit cycle; while for q=4, it has 4 small limit cycles and 1 big limit cycle; and when q⩾5, there is only 1 small limit cycle. For fourth-order systems, the cases for even q are the same as the cubic-order systems. When q=5 it can have 10 small limit cycles; while for q⩾7, there exists only 1 small limit cycle. The case q=3 is not considered in this paper. Numerical simulations are presented to illustrate the theoretical results

No full textInvariant constituents and invariant blocks under coprime action
No full textAbstractLet A and G be finite groups with (|A|,|G|)=1. We assume that A acts on G via automorphism. Let N be an A-invariant normal subgroup of G. Let ϕ be an A-invariant irreducible Brauer character of N. If A is of prime power order, then the induced Brauer character ϕG contains an A-invariant irreducible constituent; If G/N is p-solvable, then ϕG contains an A-invariant irreducible constituent. Let B be an A-invariant block of G. Then under Glauberman–Isaacs correspondence, the set IrrA(B) is a union of blocks of CG(A), say b1,b2,…,bs. Let Qi be a defect group of bi. Then there is a defect group D of B such that Qi⩽D
