On the solution of a quasilinear differential system with periodic coefficients

The existence of a partial solution is proved for a quasilinear differential system whose coefficients are representable by a trigonometric series with slowly varying coefficients and frequency. The solution obtained has the same structure.Translated from Ukrainskii Matematicheskii Zhurnal, Vol. 45, No. 8, pp. 1157–1161, August, 1993.     

Thermoelectric power of TTT2I3+δ

We have measured the thermoelectric power of crystals of TTT₂I_3+δ with conductivity maximum occuring at temperatures from 110 K to 38 K. We find that the metallic state is stabilized to lower temperatures as the samples become less stoichiometric, that the change in electron concentrations on TTT varies by about 5% over this range and that Coulomb correlations are small in this compound.
