Conformal transformations of the following kinds are compared: (1) conformal coordinate transformations, (2) conformal transformations of Lagrangian models for a D-dimensional geometry, given by a Riemannian manifold M with metric g of arbitrary signature, and (3) conformal transformations of (mini-)superspace geometry. For conformal invariance under this transformations the following applicati...

     In this article we introduce the notion of textit{Fractal $omega$-operad} emerging from  a natural $omega$-operad associated to any coglobular object in the category of higher operads in Batanin's sense, which in fact is a coendomorphism $omega$-operads. We have in mind coglobular object of higher operads which algebras are kind of higher transformations. It follows that this natural $omeg...

for the first time, it is mentioned in the interpretation of muqātil bin sulayman that: ‘nadr ibn al-harith, who was familiar with the traditions of ancient iran, claimed that the qur’an contained ‘legends of the ancients’; i.e. stories like those of rostam and esfandiyār. following muqātil, commentators often quoted this view, associating and translating ‘legends of the ancients’ with and into...

in his paper mentioned in the title, which appears in the same issue of this journal, mehdi radjabalipour derives the cyclic decomposition of an algebraic linear transformation. a more general structure theory for linear transformations appears in irving kaplansky's lovely 1954 book on infinite abelian groups. we present a translation of kaplansky's results for abelian groups into the...

OBSTETRIC shock is one of the most serious of the accidents associated with childbirth. Puerperal sepsis is the only condition responsible for a larger proportion of maternal deaths. Out of 141 consecutive deaths occurring in the Belfast Maternity Hospital, and the Royal Maternity Hospital, Belfast, during the ten years, 1927-36, twenty-three, i.e., 16.3 per cent., were due to obstetric shock. ...

the main purpose of this paper is to define a new regular matrix by using fibonacci numbers and to investigate its matrix domain in the classical sequence spaces $ell _{p},ell _{infty },c$ and $c_{0}$, where $1leq p

we find a criterion for a morphism of coalgebras over a barr-exact category to be effective descent and determine (effective) descent morphisms for coalgebras over toposes in some cases. also, we study some exactness properties of endofunctors of arbitrary categories in connection with natural transformations between them as well as those of functors that these transformations induce between co...

When facing the challenge of preserving cultural heritage for future generations, it becomes important to talk about transformations and perspectives these transformations. Thus, this integrative review article seeks discuss their tourism development, by analyzing various theoretical empirical literature sources. The results analysis highlighted importance paying attention three layers perspect...

In this work are studied the Jacobians of certain singular transformations and the corresponding measures which support the jacobian computations.
