Fourier method for a quasilinear parabolic equation with periodic boundary condition
(Hacettepe University, 2008)
A multidimensional mixed problem with Neuman type periodic boundary condition is studied for the quasilinear parabolic equation ?u/?t-a2 ?2u/?x2 = f(t, x, u). The existence, uniqueness and also continuity of the weak ...
Lattice operations of positive bilinear mappings
(Mathematical Society of the Rep. of China, 2008)
In this paper we establish extension theorems for additive mappings ? : A+ ×B+ ? C+, where A, B are Riesz spaces (lattice ordered spaces or vector lattices) and C is an order complete Riesz space, to the whole of A×B, ...
Fourier method for a quasilinear pseudo-parabolic equation with periodic boundary condition
(2009)
A multidimensional mixed problem with Neuman type periodic boundary condition is studied for quasilinear pseudo-parabolic equation ?u/?ta2 ?2u/?x2 - ? ?3u/?t?x2 = f(t, x, u). The existence, uniqueness and also convergence ...
Family of surface with a common null geodesic
(2009)
We analyzed the problem of finding a surfaces family through a null curve with Cartan frame. We constructed a differential equation system such that a given null curve is an isogeodesic curve on a surface. In addition, ...
