Lacunary almost convergence and some new sequence spaces

8th International Conference on Mathematical Analysis, Differential Equation and Applications (MADEA) -- JUN 17-23, 2018 -- Cholpon Ata, KYRGYZSTAN WOS: 000496192400014 In this paper we study some new sequence spaces of strongly lacunary almost summable sequences, which naturally come up for investigation and which will fill up a gap in the existing literature. Some topological results, a characterization of strongly lacunary almost regular matrices, uniqueness of generalized limits and inclusion relations of such sequences have been observed.
