Recurrence Sequences
Introduction The importance of recurrence sequences hardly needs to be explained. Their study is plainly of intrinsic interest and has been a central part of number theory for many years. Moreover, these sequences appear almost everywhere in mathematics and computer science. For example, the theory of power series representing rational functions [55], pseudo-random number generators ([48], [49]...
متن کاملSurvival and Recurrence in Non-melanoma Skin Cancers of scalp
Abstract Introduction: Non-melanoma scalp skin cancers (NMSCs) including squamous cell carcinomas (SCCs) and basal cell carcinomas (BCCs) are common. To manage such cancers, especially SCCs, more attention should be paid to their invasive characteristics. Mortality surveillance of SCCs and BCCs of scalp helps to choose proper approaches. Methods: The current retrospective, descriptive study w...

متن کاملRigidity and Non-rigidity Results on the Sphere
It is a simple consequence of the maximum principle that a superharmonic function u on Rn(i. e. ∆u ≤ 0) which is 1 near infinity is identically 1 on Rn (throughout this paper, n ≥ 3). Geometrically this means that one can not conformally deform the Euclidean metric in a bounded region without decreasing the scalar curvature somewhere. In fact there is a much stronger result: one can not have an...
متن کاملIntersections of Recurrence Sequences
We derive sharp upper bounds for the size of the intersection of certain linear recurrence sequences. As a consequence of these, we partially resolve a conjecture of Yuan on simultaneous Pellian equations, under the condition that one of the parameters involved is suitably large.
