On the Norms of Circulant and Circulant Matrices With the Hyperharmonic Fibonacci Numbers
In this paper, we study norms of circulant and circulant matrices
involving harmonic Fibonacci and hyperharmonic Fibonacci numbers. We obtain
inequalities by using matrix norms
On the Harmonic and Hyperharmonic Fibonacci Numbers
In this paper, we study the theory of the harmonic and the hyperharmonic
Fibonacci numbers. Also, we get some combinatoric identities like as harmonic
and hyperharmonic numbers and we obtain some useful formulas for
, which is finite sums of reciprocals of Fibonacci numbers. We
obtain spectral and Euclidean norms of circulant matrices involving harmonic
and hyperharmonic Fibonacci numbers
GCD matrices, posets, and nonintersecting paths
We show that with any finite partially ordered set one can associate a matrix
whose determinant factors nicely. As corollaries, we obtain a number of results
in the literature about GCD matrices and their relatives. Our main theorem is
proved combinatorially using nonintersecting paths in a directed graph.Comment: 10 pages, see related papers at http://www.math.msu.edu/~saga

WOS: 000434277000016In this paper, we study the spectral norms of the geometric circulant matrices T-r* = Ctirc,*(T-0, T-1, . . . ,Tn-1) and the symmetric geometric circulant matrices STr* = SCirc(r)* (T-0, T-1, . . . ,Tn-1), where T-n denotes the nth Tribonacci number and r is any complex number

WOS: 000421187900016In this study, we defineq - Bernoulli matrix B(q) and q-Bernoulli polynomial matrix B(x,q) by using q -Bernoulli numbers, and polynomials respectively. We obtain some properties of B (q) and B(x,q) We obtain factorizations q -Bernoulli polynomial matrix and shifted q -Bernoulli matrix using special matrices
Some Combinatorial Identities of q-Harmonic and q-Hyperharmonic Numbers
WOS: 000383001400001In this paper, by means of q-difference operator we derive q-analogue for several well known results for harmonic numbers. Also we give some identities concerning q-hyperharmonic numbers
On the bounds for the spectral norms of geometric circulant matrices
In this paper, we define a geometric circulant matrix whose entries are
the generalized Fibonacci numbers and hyperharmonic Fibonacci numbers.
Then we give upper and lower bounds for the spectral norms of these
matrices
