2013 Abstract and Applied Analysis  
We have considered linear partial differential algebraic equations (LPDAEs) of the form ( , ) + ( , ) + ( , ) = ( , ), which has at least one singular matrix of , ∈ R × . We have first introduced a uniform differential time index and a differential space index. The initial conditions and boundary conditions of the given system cannot be prescribed for all components of the solution vector here. To overcome this, we introduced these indexes. Furthermore, differential transform method has been
