Spectral methods for small sample time series: A complete periodogram approach
Sourav Das, Suhasini Subba Rao, Junho Yang
The periodogram is a widely used tool to analyze second order stationary time series. An attractive feature of the periodogram is that the expectation of the periodogram is approxi…
Further results on weighted core inverse in a ring
Sourav Das, Jajati Keshari Sahoo, Ratikanta Behera
The notion of the weighted core inverse in a ring with involution was introduced, recently [Mosic et al. Comm. Algebra, 2018; 46(6); 2332-2345]. In this paper, we explore new repre…
Generalized Core Inverse in a proper -ring
Jajati Keshari Sahoo, Ratikanta Behera, Sourav Das +2
In this paper, we introduce the notion of weak core and central weak core inverse in a {\it proper -ring}. We further elaborate on these two classes by producing a few represent…
Geometric properties of the four parameters Wright function
Sourav Das, Khaled Mehrez
In this paper, four parameters Wright function is considered. Certain geometric properties such as starlikeness, convexity, uniform convexity and close-to-convexity are discussed f…
