a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

We study G L ( 2 ) -structures on differential manifolds. A -structure is a smooth field of rational normal curves in the tangent bundle manifold. provide an explicit construction canonical connection for any dimension greater than 3. Moreover, we prove that even-dimensional manifold defines certain almost-complex structure over original Further, exploit to various notions integrability -struct...
