ss of geometric objects. One of the most widely studied type of geometric objects are manifolds; the two-dimensional version of a manifold is a surface, which we will define rigorously in the next section.

Fabrice JaumontBolzano theorem (§3.5), nominally a theorem about bounded sequences, is in essence a property of closed intervals; Cauchy’ criterion (§3.6) is a test for convergence, especially useful in the theory of infinite series (§10.1). The chapter concludes with a dissection of convergence into two more general limiting operations.

Fabrice Jaumont of the series. The symbols in (9.1) not only define an infinite series but also are used as an expression for the sum of the series when it converges. To avoid this ambiguity we define an infinite series in terms of ordered pairs.

Fabrice JaumontThis chapter will be devoted to the study of two classes of rings, namely, semiperfect rings and left (resp., right) perfect rings. The notion of semiperfect rings is left-right symmetric, while left (resp., right) perfect rings are always semiperfect.

Fabrice Jaumont This means may be either manual (as in DL*.) , or extremely sophisticated automatic (further research is suagested). Thus, the originally stated goal of this research , namely, the creation and Implementation of an efficient search directed question answering system, became essentially the task of
