报告摘要：We introduce the shifted Bernoulli numbers as a different natural extension of the classical Bernoulli numbers, in particular, in terms of determinant expressions.  These numbers include the reciprocal of factorial. On the other hand, Fubini numbers form an integer sequence in which the $n$th term counts the number of weak orderings of a set with $n$ elements.  We also introduce the shifted Fubini numbers as one kind of their generalizations and show several similar properties. Though Bernoulli numbers and Fubini numbers do not seem to be so related each other, the shifted Bernoulli numbers and shifted Fubini numbers have several relations.
