Circular Super patterns and Zigzag constructions
Hariprasad Manjunath, Raisa Dsouza
In this article, we introduce the notion of circular k-superpatterns, defined as permutations that contain all length-k patterns up to rotation equivalence. We present a constructi…
On the Sombor index of the total graph and the unit graph of commutative rings
Abhishek Vaibhav Pathak, Anukul Sachan, Raisa DSouza
In this paper, we investigate the Sombor index of the total graph and unit graph of which is denoted by and respectively for $n…
On a McCoy-like condition for rings
Sharang Thimmaiah, Raisa DSouza
We study rings for which whenever non-zero polynomials and satisfy , it implies that there is a non-zero element such that .…
Two Laplacians for the resistance distance matrix of a graph
Shivani Tushar Parab, Raisa DSouza
In this paper, we present two new matrices, namely the resistance Laplacian and resistance signless Laplacian matrix of a connected graph. We provide a generalized form of these ma…
Extensions of I-Reversible Rings
Vivek Bhabani Lama, Suhas B N, Susobhan Mazumdar +1
A ring is said to be i-reversible if for every , is a non-zero idempotent implies is an idempotent. It is known that the rings and (t…
Results on the topology of generalized real Bott manifolds
Raisa Dsouza, V Uma
Generalized Bott manifolds (over and ) have been defined by Choi, Masuda and Suh. In this article we extend the results of arXiv:1609.05630 on the topology o…
On the topology of real Bott manifolds
Raisa Dsouza
The main aim of this article is to give a necessary and sufficient condition for a real Bott manifold to admit a spin structure and further give a combinatorial characterization fo…
Some results on the topology of real Bott towers
Raisa Dsouza, V. Uma
The main aim of this article is to study the topology of real Bott towers as special and interesting examples of real toric varieties. We first give a presentation of the fundament…
