A similarity solution is obtained for a two-dimensional heat flow problem with unidirectional diffusion and an evolutionary, oblique boundary condition. The problem also can be interpreted in a ...

As pinch-off is approached, the length and timescales near the singularity become much smaller than the scale of the initial conditions that caused the singularity to form. In this regime the ...

Coagulation–fragmentation equations model the time evolution of systems in which particles or clusters dynamically merge or break apart. These equations play a crucial role in diverse fields ranging ...
