Lambda代数与Sq_0

The Lambda algebra and Sq_0

J H Palmieri

摘要:

Sq在Steenrod代数的上同调上的作用是由Lambda代数的自同态θ诱导的。为了理解Sq的作用,研究了Theta的性质,主要结果是Sq在小于4的滤子中是内射的,并计算了它在4-线上的核.

英文摘要:

The action of Sq on the cohomology of the Steenrod algebra is induced by an endomorphism Theta of the Lambda algebra. This paper studies the behavior of Theta in order to understand the action of Sq; the main result is that Sq is injective in filtrations less than 4, and its kernel on the 4-line is computed.
