ABSTRACT
We formulate p-adic analogues of the o-minimal group conjectures from the works of Hrushovski, Peterzil and Pillay [J. Amer. Math. Soc., to appear] and Pillay [J. Math. Log. 4 (2004) 147â€“162]; that is, we formulate versions that are appropriate for groups G definable in (saturated) P-minimal fields. We then restrict our attention to saturated models K of Th(â„šp) and Th(â„šp, an), record some elementary observations when G is defined over the standard model â„šp, and then make a detailed analysis of the case where G = E(K) for E an elliptic curve over K. Essentially, our P-minimal conjectures hold in these contexts and, moreover, our case study of elliptic curves yields counterexamples to a more naive direct translation of the o-minimal conjectures.

In this paper, we realized all finite-dimensional irreducible representations of the Lie group of class G2 in spaces of complex-valued polynomials of six variables. This realization is applied to the problem of restriction of representations of a Lie group of class G2 to a Lie subgroup of class A2.

Given a strict Lie 2-algebra, we can integrate it to a strict Lie 2-group by integrating the corresponding Lie algebra crossed module. On the other hand, the integration procedure of Getzler and Henriques will also produce a 2-group. In this paper, we show that these two integration results are...

We reformulate the inductive McKay condition, from Isaacsâ€“Malleâ€“Navarro, and apply the new criterion to simple groups of Lie type, when the prime is the defining characteristic p. Using a recent result of Maslowski, we obtain that these simple groups satisfy the inductive McKay...

Let F be a free Lie algebra of rank n â‰¥ 2 and A be a free abelian Lie algebra of rank m â‰¥ 2. We prove that the test rank of the abelian product F Ã— A is m. Morever we compute the test rank of the algebra $F/\gamma _{k}\left( F\right) ^{^{\prime }}$.

It is well known that del Pezzo surfaces of degree 9 âˆ’ n one-to-one correspond to flat En bundles over an elliptic curve. In this paper, we construct ADE-bundles over a broader class of rational surfaces that we call ADE-surfaces, and extend the above correspondence to all flat G-bundles...

We show that every Lie algebra is equipped with a natural (1, 1)-variant tensor field, the "canonical endomorphism field", determined by the Lie structure, and satisfying a certain Nijenhuis bracket condition. This observation may be considered as complementary to the Kirillov-Kostant-Souriau...
