We illustrate the solvability through weak-renormalized solutions for an invasion system of healthy tissue by a solid tumor under the Dirichlet boundary conditions and the assumptions of no growth conditions and integrable data. This model consists of four parameters: tumor cell density, matrix degradation enzyme concentration, macromolecules concentration, and oxygen concentration.

实体瘤入侵模型的可解性

我们通过Dirichlet边界条件以及无生长条件和可整合数据的假设，通过对实体瘤侵袭健康组织的健康组织的入侵系统，通过弱重新归一化解来说明其可解性。该模型由四个参数组成：肿瘤细胞密度，基质降解酶浓度，大分子浓度和氧浓度。
