The fractional Laplacian, often known as the Riesz fractional by-product, describes an strange diffusion technique linked to random tours. The Fractional Laplacian explores functions of the fractional Laplacian in technological know-how, engineering, and different components the place long-range interactions and conceptual or actual particle jumps leading to an abnormal diffusive or conductive flux are encountered.

1, and for the purpose of reference to that theorem it should be emphasized that the coefficients of the series /*(y) are here denoted by /(n), instead of by f*(n)(n = 0, 1, 2, . ). First consider the unitary-divisor function dt such that d f ( a ) is the total number of divisors d of a 6 Q for which d and a/d are coprime. 3: Averages and densities ... 1, df(y) = [ Z ( y } } 2 / Z ( y 2 ) . 5) PROPOSITION. The average-value of the unitary-divisor function df for elements of degree N in Q is asymptotically AN/Z(q-2) as N -» oo.

1) CANONICAL PRODUCT LEMMA. (i) If f is a multiplicative function on Q then f*(y] = II 1 + f(p}yd(p) + f(p2}y28(p) + ••• + f(pr)yrd(p) + •• Hence, if f is a PIM-function, then f*(y] = n m>0 r where cr = f ( p ) {p&P}. 4: Asymptotic moments of ... where a = f ( p ) {p € P}. 2 below. 2) LEMMA. Let f denote a PIM-function on Q such that f(pT) ^ 0 for some prime-power pr £ Q. Suppose that f ( p r ) + O(tr) as r —> oo (p G P), for a constant t satisfying I < t < q0 , where q0 = min{|p| : p 6 P} and m is the least positive integer such that f ( p m ) ^ 0.

1 but, since our treatment of the latter category uses facts about it which may be less familiar to some readers, we begin with a direct discussion of J-q alone. 1) THEOREM. The total number Fq(N) of non-isomorphic modules of cardinal qN in J-q is equal to P0(q-l}qN + O (q^N) as N -> oo, where Po(y) = II^Li (^~~yr}~1 is the classical "partition" generating function. PROOF. 1: Asymptotic enumeration of ... - _-. ; monic prime polynomials p * oo r=l where Zq(y] = JJ < f 1 — ys(p'j : monic prime polynomials p € is the generating function of the semigroup Qq.
