We transfer this first orderystem problem into second order equation, then we hope to determine the coefficients of the second order equation.1.Introduction 1.Second Order Equation 3.Some Lemmas 4.Proof of the Main Result 11.The Relation between First Order System and Second Order Equation 13.Recent Development for Caldero''n Problem 18.The Magnetic Field and the Electrical Potential for the Pauli Hamiltonian 23eferences 27application/pdf315877 bytesapplication/pdfen-USnoneDirichlet to Neumann mapmagnetic fieldelectrical potentialCauchy datathe Pauli Hamiltonianthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/180662/1/ntu-98-R95221005-1.pdf
