  • Prism Complexes 
    KALELKAR, TEJAS; Nair, Ramya (Nipissing University, North Bay, Ontario, Canada., 2023)
    A prism is the product space ∆ × I where ∆ is a 2- simplex and I is a closed interval. We introduce prism complexes as an analogue of simplicial complexes and show that every compact 3-manifold has a prism complex structure. ...
  • Essential surfaces in Seifert fiber spaces with singular surfaces 
    KALELKAR, TEJAS; NAIR, RAMYA (Elsevier B.V., 2023-09)
    Two-sided incompressible surfaces in Seifert fiber spaces with isolated singular fibers are well-understood. Frohman [3] and Rannard [6] have shown that one-sided incompressible surfaces in Seifert fiber spaces which have ...
