A Class of Baker–Akhiezer Arrangements

Characteristic Varieties for a Class of Line Arrangements

Let A be a line arrangement in the complex projective plane P, having the points of multiplicity ≥ 3 situated on two lines in A, say H0 and H∞. Then we show that the non-local irreducible components of the first resonance variety R1(A) are 2-dimensional and correspond to parallelograms P in C = P \ H∞ whose sides are in A and for which H0 is a diagonal.

A New Class of Banach Sequence Spaces

On a class of paracontact Riemannian manifold

We classify the paracontact Riemannian manifolds that their Riemannian curvature satisfies in the certain condition and we show that this classification is hold for the special cases semi-symmetric and locally symmetric spaces. Finally we study paracontact Riemannian manifolds satisfying R(X, ξ).S = 0, where S is the Ricci tensor.

A Flexible Class of Skew Logistic Distribution

‎Here we consider  a new class of skew logistic  distribution as a generalized mixture of the standard logistic and skew logistic distributions‎, ‎and study some of its important aspects‎. ‎The tail behaviour of the  distribution is compared with that of the skew logistic distribution and a location-scale extension of the distribution is proposed‎. ‎Fu...
