A partial semiring is a structure possessing an infinitary partial addition and a binary multiplication, subject to a set of axioms. The partial functions under disjoint-domain sums and functional compo- sition is a partial semiring. In this paper we obtain the characteristics of 2-absorbing primary subsemimodules and weakly 2-absorbing primary subsemimodules in partial semirings.

We study the quenching behavior of the solution of a semi- linear reaction-diffusion system with nonlinear boundary conditions. We prove that the solution quenches in finite time and its quenching time goes to the one of the solution of the differential system. We also obtain lower and upper bounds for quenching time of the solution.

Star-Hurewicz Modulo an Ideal Property In Topological Spaces 星形Hurewicz模——拓扑空间中的一个理想性质
Q4 Mathematics Pub Date : 2021-01-28 DOI: 10.18311/JIMS/2021/26630
M. Bhardwaj, B. Tyagi, Sumit Singh
In this paper, a class of star-Hurewicz modulo an ideal spaces is introduced and studied. For an ideal K of finite subsets of N, a characterization of weakly star- K -Hurewicz extremally disconnected spaces is given using ideal. It is shown that star-Hurewicz modulo an ideal property is hereditary under clopen subspaces. In this manner we obtained relationships of star-Hurewicz modulo an ideal property with other existing Hurewicz properties in literature.

The Effect of Magnetic Field on Compressible Boundary Layer by Homotopy Analysis Method 磁场对可压缩边界层影响的Homotopy分析法

We analyse the effect of applied magnetic field on the flow of compressible fluid with an adverse pressure gradient. The governing partial differential equations are solved analytically by Homotopy analysis method (HAM) and numerically by finite difference method. A detailed analysis is carried out for different values of the magnetic parameter, where suction/ injection is imposed at the wall. It is also observed that flow separation is seen in boundary layer region for large injection. HAM is a series solution which consists of a convergence parameter h which is estimated numerically by plotting h curve. Singularities of the solution are identified by Pade approximation.
我们分析了外加磁场对具有反向压力梯度的可压缩流体流动的影响。控制偏微分方程的解析解采用同源分析法,数值解采用有限差分法。对磁性参数的不同值进行了详细分析,其中在壁处施加吸力/喷射。还观察到,对于大的注入,在边界层区域可以看到流动分离。HAM是一个由收敛参数h组成的级数解,通过绘制h曲线对收敛参数h进行数值估计。该解的奇异性是由帕德近似确定的。

In this paper, we discuss group analysis of rst-order delay partial di erential equations and use it to obtain symmetries of the Invis- cid Burgers' equation with delay, its kernel and extensions of the kernel. We obtain a Lie type invariance condition for rst-order delay partial di erential equations by using Taylor's theorem for a function of several variables. We obtain the symmetries admitted by this delay partial di er- ential equation. Further, we obtain representations of analytic solutions and the reduced equations from the symmetries.
