  • Nested radicals and coinduction principle 
    Ratnayake, J. K.; Annanthakrishna, M.; Senadheera, J. N. (University of Jaffna, 2022)
    Infinite nested radicals of the form ±�2 ± �2 ± √2 ± ⋯ arise from the iterated function system ±√2 ± x. These functions can be combined to construct a coalgebra α:[−2,2] → F([−2,2]) for an endofunctor F on the category of ...
  • A hybrid forecasting model for monthly elevation-wise tea auction prices in Sri Lanka using supply and demand factors 
    Siriwardana, K. M. M. H.; Deshani, K. A. D.; Wickramarachchi, D. S. (University of Jaffna, 2022)
    Tea is a major agricultural commodity in Sri Lanka’s plantation-based economy. Tea growing areas in Sri Lanka are divided into three regions based on elevation: high, medium, and low. Elevation at which tea is grown has a ...
  • Ip-Connectedness and Ip-compactness in ideal topological spaces 
    Rakshana, S.; Elango, P. (University of Jaffna, 2022)
    In ideal topological spaces, we introduce a new class of generalized closed sets known as Ip-closed sets. A subset A of an ideal topological space (X, τ, I) is said to be Ip-closed set if A∗ ⊆ U whenever A ⊆ U and U is ...
