( x ) has 1 good root and Q P,n,k,c
( x ) has 1 optimistic root and Q P,n,k,c ( x ) 0 for any x 0; If B 0 and B2 – 4AC 0, i.e., B -2 AC, then Q P,n,k,c ( x ) has two distinct good roots; Q P,n,k,c ( x ) 0 when x lies outside the two roots and Q P,n,k,c ( x ) 0 when x lies in between the two roots. Now, we explicitly calculate the option, Methyl jasmonate custom synthesis denoted by x0 , of Q P,n,k,c ( x ) = 0. By a direct calculation, B -2 AC resp., B -2 AC if and only if P D (n, k, c) resp., P D (n, k, c) , where D (n, k, c) =(n – 1)(n – 2k)2 c . n(n2 – 2kn – n 2k2 ) 2n k(k – 1)(n – k)(n – k – 1)(32)It really is not tough to confirm that D (n, k, c) is actually a strictly decreasing function of k for 1 k n ; two hence, n-2 n c, 0 = D (n, , c) D (n, k, c) D (n, 1, c) = two n i.e., D (n, k, c) is often a optimistic continuous and D (n, k, c) c for two k n . two For the case of P D (n, k, c), i.e., B -2 AC, the two good roots of Q P,n,k,c ( x ) = 0 are provided by – B B2 – 4AC two x0 = . (33) 2A It truly is simple to check that B2 – 4AC = (n – 1)2 (n – 2k )two , exactly where is = ( n – 1)2 nP – (n – 2k)c-4nk (k – 1) Pc . n-(34)So, substituting A, B and C into (33), the squared of the two roots, denoted by ( P, n, k, c) and ( P, n, k, c), in the answer Q P,n,k,c ( x ) = 0 are given, respectively, by(n – 1) (n – 1)(n – 2k)two ( P – c) 2k(n – k)(n – two) P – (n – 2k)( P, n, k, c) =(n – 1) (n – 1)(n – 2k)two ( P – c) 2k(n – k)(n – 2) P (n – 2k)( P, n, k, c) = 2n(k – 1)(n – k – 1) .2n(k – 1)(n – k – 1),(35)For the circumstances of P = D (n, k, c), i.e., B = -2 AC, then = 0 and ( P, n, k, c) = ( P, n, k, c), that is definitely to say, Q P,n,k,c ( x ) has one optimistic root. To sum up, Lemma 3 follows.Lemma 4. Let Mn (n 3) be a total spacelike hypersurface with continuous normalized scalar n curvature inside a Ricci symmetric manifold L1 1 satisfying (1) and (2). Let us suppose that P c n ; then, there exists a sequence of points q n and H is bounded on M N M such that lim nH (q ) = sup nH,Mlim | nH (q )| = 0 and lim sup (nH )(q ) 0.Proof. We observe that, if H vanishes identically on Mn , then the result is valid. So, let us suppose that H just isn’t identically zero. This way, we can pick out the orientation of Mn such that sup H 0.Mathematics 2021, 9,10 ofn Let us decide on a regional orthonormal frame field ei i=1 such that hij = i ij . Because P c, 2 S n2 H two , which shows that it follows, from (17), that i0 n | H | – | i |.(36)Taking collectively (36) with (two) and (15) results in Rijij c2 – i j c2 – n2 H two , i.e., the sectional curvatures of Mn are bounded from GNF6702 site beneath since H is bounded. Hence, we may apply Omori’s maximum principle [28] towards the function nH and acquire a sequence of points q Mn such that lim nH (q ) = sup nH, limnH (q ) = 0 and lim sup nHii (q ) 0.(37)Due to the fact sup H 0, taking subsequences if important, we are able to arrive to a sequence q Mn which satisfies (37) and such that H (q ) 0. Then, from (36), we acquire 0 nH (q ) – |i (q )| nH (q ) |i (q )| 2nH (q ). (38)Note that H is bounded; hence, nH (q ) – i (q ) can be a non-negative and bounded sequence. Evaluating (nH ) at q , taking the limit and working with (37) and (38), we have lim sup(nH )(q ) lim sup (nH – i )(q )nHii (q ) 0.iThis completes the proof of Lemma four. five. Proof of Theorem two Proof of Theorem 2. Because the continual P c for any two k and Lemmas 1 and 2, we haven two,by the inequality (19)(nH )1 ||2 Q P,n,k,c (||). n-(39)Utilizing Lemma four, there exists a sequence of points q ; evaluating (39) at this sequence, we receive 1 0 lim sup (nH (q )) sup ||two Q P,n,k,c (sup ||). (40) n-1 Now, by thinking about the range of the continuous.
