Thermoelectric effects in a Luttinger liquid (LL) wire 
 
 adiabatically connected to the leads of noninteracting electrons are considered. For a 
 
 multichannel LL a staircase-like behavior of the thermal conductance as a function of 
 
 chemical potential is found. A thermopower for a LL wire with an impurity is evaluated for 
 
 two cases: (i) LL constriction and (ii) infinite LL wire. We show that the thermopower is 
 
 described a Mott-like formula renormalized by an interaction-dependent factor. For an 
 
 infinite LL the renormalization factor decreases with increase of the interaction. However, 
 
 for a realistic situation, when a LL wire is connected to the leads of noninteracting 
 
 electrons (LL constriction), the repulsive electron-electron interaction enhances the 
 
 thermopower. A nonlinear Peltier effect in a LL is briefly discussed.
