Authors:  .
 
       
         
  Abstract:  The Omega polynomial of a connected graph G, denoted by

this paper, we obtain explicit computing formulas for Omega and Sadhana polynomials of bridge graphs and chain graphs. As applications, Omega and Sadhana polynomials of some spiro-chains composed of four-member or six-member rings are deduced.

Keywords: Quasi-ortogonal cut; Omega polynomial, Sadhana polynomial, bridge graph; chain graph
