Parity Preservation of K-Types under the Theta Correspondence
Journal of Lie Theory, Volume 28 (2018) no. 3, pp. 663-672
This note shows a property of degree-parity preservation for K-types under Howe's theta correspondence. As its application, we deduce the preservation of parity of all K-types occurring in an arbitrary irreducible (g, K)-module of any Lie group in reductive dual pairs.
