Abstract
Circulant type matrices have become an important tool in solving fractional order differential equations. In this paper, we consider the circulant and left circulant andg-circulant matrices with the Jacobsthal and Jacobsthal-Lucas numbers. First, we discuss the invertibility of the circulant matrix and present the determinant and the inverse matrix. Furthermore, the invertibility of the left circulant andg-circulant matrices is also discussed. We obtain the determinants and the inverse matrices of the left circulant andg-circulant matrices by utilizing the relation between left circulant,g-circulant matrices, and circulant matrix, respectively.

Summary
Circulant type matrices possess interesting properties, which have been exploited to obtain the transient solution in a closed form for fractional order differential equations. Some authors gave the explicit determinant and inverse of the circulant and skewcirculant matrix involving Fibonacci and Lucas numbers. In [15], the nonsingularity of circulant type matrices with the sum and product of Fibonacci and Lucas numbers is discussed. Lind presented the determinants of circulant and skew-circulant matrix involving Fibonacci numbers in [18]. Shen et al considered circulant matrices with Fibonacci and Lucas numbers and presented their explicit determinants and inverses by constructing the transformation matrices in [20]. The purpose of this paper is to obtain the better results for the determinants and inverses of circulant type matrices by some properties of Jacobsthal and Jacobsthal-Lucas numbers.
