Mass conserving global solutions for the nonlinear collision-induced fragmentation model with a singular kernel

Debdulal Ghosh, Jayanta Paul, Jitendra Kumar

摘要:

研究了粒子过程中具有奇异碰撞核的碰撞诱导非线性碎裂模型的质量守恒整体解的存在性.上述形式包括许多奇异和非奇异类型的面向实际的内核。无界碰撞核在坐标轴上的奇异性扩展了以前的存在性结果,并且在无穷远处最多表现出二次增长。最后,讨论了解的唯一性.

英文摘要:

This article is devoted to the study of existence of a mass conserving global solution for the collision-induced nonlinear fragmentation model which arises in particulate processes, with the singular type of collision kernel. The above mentioned form includes many practical oriented kernels of both singular and non-singular types. The singularity of the unbounded collision kernel at coordinate axes extends the previous existence result and also exhibits at most quadratic growth at infinity. Finally, uniqueness of solution is also investigated.
