I-convergent sequences defined by a modulus function. They are defined using by a phi-function, a A = (a(nk)) real matrix and an ideal I of positive integers. We define N-theta(A, phi, f) I and S-theta(A, phi) I spaces and study their relation.eninfo:eu-repo/semantics/closedAccessLacunary sequenceideal convergencemodulus functionConference Object1558774779N/AWOS:000331472800184N/A2-s2.0-8488753902210.1063/1.4825608
