Let T

be the full transformation semigroup on a set X,
TE*(X)={a ? TX:"x,y ? X, (x,y) ? E? (xa,ya) ? E}T_{E^*}(X)=\{\alpha\in T_X:\forall x,y\in X, (x,y)\in E\Leftrightarrow (x\alpha,y\alpha)\in E\} 相似文献

On each compact Riemann surface Σ of genusp≥1, we have the Bergman metric obtained by pulling back the flat metric on its Jacobian via the Albanese map. Taking theL
2-product of holomorphic quadratic differentials w.r.t. this metric induces a Riemannian metric on the Teichmüller spaceT
p that is invariant under the action of the modular group. We investigate geometric properties of this metric as an alternative
to the usually employed Weil-Petersson metric.

The problem under consideration is the following: Let S: E′ → Lq, T: E′ → Lp, 0 < q ≦ 2, 0 < p ≦ 2, be operators, ‖Sa‖ ≦ ‖Ta‖, such that, T generates a stable measure on E, i.e., exp (-‖Ta‖ p), a ? E′, is the characteristic function of a RADON measure on E. Does this imply, that exp (-‖Sa‖ q), a ? E′, is the characteristic function of a RADON measure, too? In general this is not true provided q or p less than 2. A BANACH space is said to be of (q,p)-cotype if the answer to the above question is “yes”. We establish several properties of this classification and obtain as an application the well-known classes due to MOUCHTARI, TIEN, WERON and MANDREKAR, WERON, Finally we apply our results to so-called S-spaces. 相似文献

Green’s relations and regularity for semigroups of transformations that preserve double direction equivalence 总被引:1,自引:0,他引:1
Let T X denote the full transformation semigroup on a set X. For an equivalence E on X, let $T_{E^*}(X)=\{\alpha\in T_X:\forall x,y\in X,(x,y)\in E\Leftrightarrow(x\alpha,y\alpha)\in E\}.$ Then $T_{E^{*}}(X)
