| contents | A monogenic function of two vector variables is a function annihilated by the operator consisting of two Dirac operators, which are associated to two variables, respectively. We give the explicit form of differential operators in the Dirac complex resolving this operator and prove its ellipticity directly. This open the door to apply the method of several complex variables to investigate this kind of monogenic functions. We prove the Poincaré lemma for this complex, i.e. the non-homogeneous equations are solvable under the compatibility condition by solving the associated Hodge Laplacian equations of fourth order. As corollaries, we establish the Bochner--Martinelli integral representation formula for this differential operator and the Hartogs' extension phenomenon for monogenic functions. We also apply abstract duality theorem to the Dirac complex to obtain the generalization of Malgrange's vanishing theorem and establish the Hartogs--Bochner extension phenomenon for monogenic functions under the moment condition. |
