Mapping Between Antisymmetric Tensor And Weinberg Formulations
  In the framework of the classical field theory a mapping between antisymmetric tensor matter fields and Weinberg's $2(2j+1)$ component "bispinor" fields is considered. It is shown that such a mapping exists and equations which describe the $j=1$ antisymmetric tensor field coincide with the Hammer-Tucker equations completely and with the Weinberg ones within a subsidiary condition, the Klein-Gordon equation. A new Lagrangian for the Weinberg theory is proposed. It is scalar, Hermitian and contains only the first-order time derivatives of the fields. The remarkable feature of this Lagrangian is the presence of dual field functions, considered as parts of a parity doublet. I study then origins of appearance of the dual solutions in the Weinberg equations on the basis of spinorial analysis and point out the topics which have to be explained in the framework of a secondary quantization scheme.
