Our thesis is to study whether or not homogeneous polynomial space can be reduced to a direct sum of irreducible osp-modules. Our conclusion is for any odd homogeneous polynomial space, the answer is yes. For even, the answer is no in the case of degree 2, and therefore invalid for any even homogeneous polynomial space since it must contain a submodule isomorphic to degree 2 homogeneous polynomial space. However, a complete decomposition of arbitrary even homogeneous polynomial space has not been reached yet.Title i Contents ii Acknowledgements vii Abstract in Chinese viii Abstract ix 1 Introduction 1 1.1 Realization of Lie Algebra gl as Linear Differential Operators 2 1.2 The Lie Algebra so times sp 3 1.3 The Lie Algebra osp 4 2 osp(4,4) acting on S^{2k-1}(V) 5 2.1 osp(4,4) acting on S^1(V) 5 2.2 osp(4,4) acting on S^3(V) 6 2.3 osp acting on S^{2k-1}(V) 10 3 osp(4,4) acting on S^{2k}(V) 12 3.1 osp(4,4) acting on S^2(V) 12 3.2 osp(4,4) acting on S^4(V) 14 References 17524386 bytesapplication/pdfen-US李代數張量Lie algebratensorthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/59451/1/ntu-94-R91221011-1.pdf
