%0 Journal Article %T d-records in geometrically distributed random variables %A Helmut Prodinger %J Discrete Mathematics & Theoretical Computer Science %D 2006 %I Discrete Mathematics & Theoretical Computer Science %X We study d¨Crecords in sequences generated by independent geometric random variables and derive explicit and asymptotic formul for expectation and variance. Informally speaking, a d¨Crecord occurs, when one computes the d¨Clargest values, and the variable maintaining it changes its value while the sequence is scanned from left to right. This is done for the ¡°strict model,¡± but a ¡°weak model¡± is also briefly investigated. We also discuss the limit q ¡ú 1(q the parameter of the geometric distribution), which leads to the model of random permutations. %U http://www.dmtcs.org/dmtcs-ojs/index.php/dmtcs/article/view/543
