We prove that commutative power associative nilalgebras of nilindex n and dimension n are nilpotent of index n. We find a necessary and sufficient condition for such an algebra to be a Jordan algebra and give all corresponding isomorphism classes.

✦ Synopsis
We show that noncommutative power-associative nilalgebras of finite dimension n and nilindex k are solvable if k s n q 1 or k s n. For any given integer n ) 2, we present an example of a power-associative nilalgebra of dimension n and nilindex n y 1 which is not solvable. This implies a power-associative nilalgebra of dimension n and nilindex k need not be solvable if kn. ᮊ 2001 Academic Press Recall that a nonassociative algebra J is called sol¨able if the descend-Ž1.

In this paper we study surjectivity of the map g → g n on an arbitrary connected solvable Lie group and describe certain necessary and sufficient conditions for surjectivity to hold. The results are applied also to study the exponential maps of the Lie groups. 2002 Elsevier Science (USA)
## Abstract Family‐based association tests (FBATs) provide simple and powerful tests to detect association between a genetic marker and a disease‐susceptibility locus, manifest in subjects by a phenotype or disease trait. Here we propose a new class of conditional tests for family‐based association
