There are two basic categories of reflection, according to where the learner reflects on. In self-reflection, the learner reflects on her/his own actions, while in comparative reflection the learner reflects on others’ actions. We propose an alternative reflection type, as a subcategory of the comparative reflection, the analogical reflection. In analogical reflection, students reflect on analo...

Reflection equation algebras and related Uq(g)-comodule algebras appear in various constructions of quantum homogeneous spaces and can be obtained via transmutation or equivalently via twisting by a cocycle. In this paper we investigate algebraic and representation theoretic properties of such so called ‘covariantized’ algebras, in particular concerning their centres, invariants, and characters...

During the past 23 years since I wrote Bodymind Energetics, the Complementary and Alternative Medicine professions as a collective phenomenon have evolved greatly, much in the direction I had anticipated. The only problem is that the AOM profession, intently focused as it was on establishing its own professional identity, tended to ignore the fact that to the average CAM practitioner, and to co...

gabriel garcía márquez is one of the most outstanding cultural, political and social figures in latin america. apparently iranian writers have been greatly influenced by him and we can perceive the reflection of his words, his style, or in general, his voice in the works of many persians writers. in this research we have done an intertextual-comparative-study on the reflection of one hundred ye...

With any involutive anti-algebra and coalgebra automorphism of a quasitriangular bialgebra we associate a reflection equation algebra. A Hopf algebraic treatment of the reflection equation of this type and its universal solution is given. Applications to the twisted Yangians are considered.
