It is shown that if a linearly ordered set B does not contain as subsets sets of order type
and
*
then B can be embedded in 2
. We construct an example of a set satisfying the above conditions which cannot be embedded in any 2
if <
. Simultaneously we show that for any ordinal, 2
+1
cannot be embedded in 2
and that there exists at least
+1
distinct dense order types of cardinality 2

A result of Neisendorfer says that, for every connected p-complete finite complex Y with 2Y torsion, the p-completion of PK(/p, 1) (Ym) and Y are of the same homotopy type for any positive integer m. Here, PK(/p, 1)(Ym) is the periodization functor of Bousfield and Ym) is the m-connective cover of the space Y. The proof of this result depends on Millers Theorem of Sullivans conjecture. The aim in this paper is to study the phenomenon without the use of Millers Theorem.AMS Subject Classification (2000): 55P60 相似文献

LetX, Y be finite sets and suppose thatF is a collection of pairs of sets (F, G),FX,GY satisfying |FF|s, |GG|t and |FF|+|GG|s+t+1 for all (F, G),F, GF. Extending a result of Sali, we determine the maximum ofF. 相似文献

This paper concerns the investigation of the stabilization of solutions of the Cauchy problem for a system of equations of the form u/t = u + fi(u, v); v/t = v + F2(u, v). It is proved that under certain assumptions the behavior of solutions as t is determined by mutual arrangement of the set of initial conditions {(u, v): u = f1(x), v =f
2(x), xRn} and the trajectories of the system of ordinary differential equations du/dt = F1(u, v), dv/dt = F2(u, v). The question of stabilization of the solutions of a single quasilinear parabolic equation is also considered.Translated from Matematicheskie Zametki, Vol. 3, No. 1, pp. 85–92, January, 1968. 相似文献

Let X and Y be locally compact-compact topological spaces, F X×Y is closed, and P(F) is the set of all Borel probability measures on F. For us to find, for the pair of probability measures (x, y P (X)×P(Y), a probability measure P(F) such that
