Let F be an algebraically closed field of characteristic zero, and G be a finite abelian group. If A = circle times(g is an element of G)A(g) is a G-graded algebra, we study degree-inverting involutions on A, i.e. involutions ...

In this paper we obtain a result on simultaneous linearization for a class of pairs of involutions whose composition is normally hyperbolic. This extends the corresponding result when the composition of the involutions is ...

Let D be a division ring with center k, and let D-dagger be its multiplicative group. We investigate the existence of free groups in D-dagger, and free algebras and free group algebras in D. We also go through the case ...

Let phi: a"e(2) -> a"e(2) be an orientation-preserving C (1) involution such that phi(0) = 0. Let Spc(phi) = {Eigenvalues of D phi(p) | p a a"e(2)}. We prove that if Spc(phi) aS, a"e or Spc(phi) a (c) [1, 1 + epsilon) ...

This study aimed to evaluate the effect of chloprostenol administration, at early or intermediary puerperium, under uterine involution, intrauterine fluid accumulation and ovarian activity return. 30 Murrah postpartum ...

Aiming monitoring uterine involution in five buffalo from parturition to 50th day of puerperium, daily sonographic examinations were carried out and uterine and cervical diameter, appearance of uterine wall and caruncucles, ...
