“…We denote the difference between the parameter and the critical value by α = τ − τ k , and use the notation y s (u) = y(s + u), −1 ≤ u ≤ 0 for solutions segments, as usual. Let L and F be defined by the relation 1) , where L(α) is a linear operator, F (0, 0) = 0 and D 1 F (0, 0) = 0. Then we have…”

“…In Section 2, we prove that this long formula for Re C 1 (0) is always negative, and this holds not only for the first bifurcation point τ 0 , but for all critical parameter values τ k , k ∈ N 0 . Here we use the method of [2] (see also [1]) to obtain our main result, which is stated in the following theorem. 2 Proof of the main result…”

“…Balázs és Röst [2] dolgozatában a (3.1) egyenlet Hopf-bifurkációit tanulmányozta, ha f ∈ C 3 , f (0) = 0 és f (0) = 0. Továbbá, ha a k-adik Hopf-bifurkáció szuperkritikus, akkor µ k > 0 (µ k < 0) esetén µ > µ k -ra (µ < µ k -ra) jön létre az új periodikus pálya.…”

“…Balázs és Röst [2] dolgozatában egy egyszer ¶bb módszert mutatott be a bifurkáció irányának és a periodikus megoldások stabilitásának meghatározására, így mi is ezt a megközelítést alkalmazzuk. A (3.1) egyenlet…”
