We will consider a Trudinger-Moser inequality for the critical Sobolev space Hn/p,p(ℝn) with the fractional derivatives in ℝn and obtain an upper bound of the best constant of such an inequality. Moreover, by changing normalization from the homogeneous norm to the inhomogeneous one, we will give the best constant in the Hubert space H n/2,2(ℝn). As an application, we will obtain some lower bound of the best constant of a Gagliardo-Nirenberg inequality. Indiana University Mathematics Journal
