Radon problems for hyperboloids
Russian Universities Reports. Mathematics, 2019We offer a variant of Radon transforms for a pair X and Y of hyperboloids in R^3 defined by [x,x] = 1 and [y,y] = -1, y_1 ≥ 1, respectively, here [x,y] = -x_1 y_1+x_2 y_2+x_3 y_3. For a kernel of these transforms we take δ([x,y]), δ(t) being the Dirac delta function. We obtain two Radon transforms D(X) →C^∞ (Y) and D(Y) →C^∞ (X). We describe kernels and

Angular momentum and space–time hyperboloids
Journal of Mathematical Physics, 1995For a classical field theory, in Minkowski space–time, the field momentum and angular momentum are defined as an integral of the appropriate density over an asymptotically null hyperboloid. We prove that for the electromagnetic field these quantities are well defined even for charged sources where infrared divergences are a problem for defining the ...
