چکیده
در این مقاله مساله مقدار مرزی شوارتز از معادلات دیفرانسیل جزئی مختلط را برای معادله کشی–ریمان ناهمگن روی یک دامنه چند ضلعی با نقاط گوشه­ ای معلوم یعنی مثلث متساوی الاضلاع، به­ طور دقیق پیشنهاد می­ دهیم. با به­ کار گیری روش بازتاب پارکتینگ و انتخاب یک نقطه­ ی دلخواه از مثلث متساوی الاضلاع مورد نظر و بازتاب های مکرر آن در تمام بخش­ های مرزی از مثلث متساوی الاضلاع تمام صفحه­ ی مختلط پوشش داده می­ شود. علاوه بر این، ابزار اساسی برای حل مساله مقدار مرزی شوارتز از معادلات دیفرانسیل جزئی مختلط برای معادله کشی-ریمان، فرمول نمایش انتگرال کشی-پمپیو است. بدین ترتیب با استفاده از روش بازتاب پارکتینگ و فرمول نمایش انتگرالی کشی–پمپیو یک فرمول نمایش انتگرالی شوارتز-پواسون را روی مثلث متساوی الاضلاع و بخش­ های مرزی مختلف آن به­ طور دقیق محاسبه می­­ کنیم. هم­ چنین، رفتارهای مرزی برای عملگر از نوع شوارتز را مورد بررسی قرار می­ دهیم. سرانجام جواب دقیقی را برای مساله مقدار مرزی شوارتز از معادلات دیفرانسیل جزئی مختلط برای معادله کشی-ریمان ناهمگن روی مثلث متساوی الاضلاع ارائه می­ دهیم.

چکیده English

In this paper, we explicitly investigate the Schwarz boundary value problem of complex partial differential equations for an inhomogeneous Cauchy-Riemann equation on a polygon domain with distinct points of the equilateral triangle. By applying the technique of parquet reflection and selecting an arbitrary point of the equilateral triangle and its repeated reflections in all parts of the boundary, full page of complex spaces covered. In addition, the fundamental tool for solving the Schwarz boundary value problem from the complex partial differential equations for the Cauchy-Riemann equation is the Cauchy–Pompeiu integral representation formula. Thus, using the technique of parquet reflection and the Cauchy–Pompeiu integral representation formula, we accurately calculate the Schwarz-Poisson integral representation formula on the equilateral triangle and its different boundary portions. We also consider boundary behaviors of the Schwarz-type operator. Finally, we give an exact answer for the Schwarz boundary value problem of complex partial differential equations for an inhomogeneous Cauchy-Riemann equation on the equilateral triangle.
