Abstract: Laplace operator Δ=u2(2x+2u) has infinite discrete spectrum {λn},
Δφn+λnφn=0,φnL2(F,dμ),dμ=dxduu2(,λn0,
in fundamental domain
F={z=x+iy|y>0,|z|>1,|x|<12}
of modular group PSL(2,Z). Also, it has a continuous spectrum mapping the interval[14,+).
In his “Shur Lectures” (Tel -Aviv, 1992), P. Sarnack suggested that this discrete spectrum {λn} should play a key role in number theory.
In the talk, we will discuss a proof of the following new theorem:

Theorem. Let x3 and suppose that
0<tx4(lnxp)2,p20.
Then the following formula holds:
ψ(x)=2πtn0etr2n2kxkcos(2rnlnk)+R(x),|R(x)|cx2t(lnx)2(c(lnx)3(.
\emph{Here ψ(x) denotes Chebyshev's function, the sequence rn is defined by the relations λn=r2n+14, and c is some computable constant.}

Therefore, the fact that the discrete spectrum {λn} determine prime number distribution, is established.
