A new example of deficiency one groups
Çevik, Ahmet Sinan; Güngör, A. Dilek; Karpuz, Eylem Güzel; Ateş, Fırat; Cangül, İsmail Naci (Amer Inst Physics, 2010)The main purpose of this paper is to present a new example of deficiency one groups by considering the split extension of a finite cyclic group by a free abelian group having rank two. -
On the efficiency of semi-direct products of finite cyclic monoids by one-relator monoids
Ateş, Fırat; Karpuz, Eylem Güzel; Güngör, A. Dilek; Cevik, Ahmet Sinan; Cangül, İsmail Naci (Amer Inst Physics, 2010)In this paper we give necessary and sufficient conditions for the efficiency of a standard presentation for the semi-direct product of finite cyclic monoids by one-relator monoids. -
On the norms of toeplitz and hankel matrices with pell numbers
Karpuz, Eylem Güzel; Ateş, Fırat; Güngör, A. Dilek; Cangül, İsmail Naci; Çevik, Ahmet Sinan (Amer Inst Physics, 2010)Let us define A = [a(ij)](i,j=0)(n-1) and B = [b(ij)](i,j=0)(n-1) as n x n Toeplitz and Hankel matrices, respectively, such that a(ij) = Pi-j and b(ij) = Pi+j, where P denotes the Pell number. We present upper and lower ...
