Knots and non-orientable surfaces in 3-manifolds
Alessia Cattabriga, Paolo Cavicchioli, Rama Mishra +1
In this article, we propose a new approach for describing and understanding knots and links in a 3-manifold through the use of an embedded non-orientable surface. Specifically, we…

Knots in
Louis H. Kauffman, Rama Mishra, Visakh Narayanan
This paper studies knots in three dimensional projective space. Our technique is to associate a virtual link to a link in projective space so that equivalent projective links go to…

Plat closures of spherical braids in
Rama Mishra, Visakh Narayanan
We define plat closure for spherical braids to obtain links in and prove that all links in can be realized in this manner. Given a spherical braid $…
