Ask ChatGPT about the research

Singularities in general are considered to be one of the important issues in algebraic geometry and applied mathematics, among them the ADE or simple singularities which drew attention since they have appeared separately in various areas of scientific applications. The name comes from three graphs characterized by letters A, D and E denoting types of Lie groups. Arnold stated them in a direct manner. Many people gave studies about the subject like Roczen.M who presented the canonical resolution in dimension 3 and Char ≠ 2. giving an equivalent non-singular variety is what meant by resolution, Canonical resolution adds a description of the exceptional loci.

Research summary
تناقش الورقة البحثية التي أعدها ل. حروني و ي. الوادي من قسم الرياضيات بجامعة دمشق، سوريا، موضوع حل التفردات في الهندسة الجبرية، مع التركيز على التفردات البسيطة أو ما يعرف بتفردات ADE. هذه التفردات تمثل نقاطًا في الفضاء الجبري حيث تكون الدالة الجبرية غير قابلة للتفريق. يتم تصنيف هذه التفردات إلى ثلاثة أنواع رئيسية: A، D، و E، بناءً على مجموعات لي. تركز الدراسة على تقديم حلول لهذه التفردات في حقل ذي خاصية مختلفة عن 2، وتحديدًا في البعد الخامس. تتناول الورقة أيضًا التطبيقات المختلفة لهذه التفردات في الهندسة التفاضلية والفيزياء النظرية. يتم تقديم الحلول باستخدام تقنيات مثل النفخ (Blowing-up) ومجموعة بيكارد (Picard group) والمقسمات (Divisors)، مع التركيز على وصف المواقع الاستثنائية (Exceptional loci) التي تظهر بعد الحل. تعتمد الدراسة على أعمال سابقة لعلماء مثل أرنولد وروزن، وتقدم وصفًا دقيقًا لكيفية تحويل التفردات إلى تنوعات غير مفردة.
Critical review
دراسة نقدية: تقدم الورقة موضوعًا مهمًا ومعقدًا في الهندسة الجبرية، وتساهم في فهم أعمق للتفردات البسيطة وحلولها. ومع ذلك، يمكن أن تكون الورقة أكثر وضوحًا في شرح بعض المفاهيم الأساسية للقارئ غير المتخصص. كما أن الاعتماد الكبير على الرموز والمعادلات الرياضية قد يجعل من الصعب على البعض متابعة الأفكار المطروحة. من المفيد أيضًا تضمين أمثلة تطبيقية أكثر توضيحًا لكيفية استخدام الحلول المقدمة في مجالات مثل الفيزياء النظرية. على الرغم من ذلك، تعتبر الورقة إضافة قيمة للأدبيات العلمية في هذا المجال.

This study aims at studying the psychometric properties of The State- Trait Anger Expression Inventory (STAXI-2) on a sample students of faculty of education at Damascus University, and identifying the methods which were followed to assess the re liability and validity of the scale. The selected sample was incidental, and consisted of (367) students of the Education faculty at Damascus University.
This paper discusses the escape velocity for a limited material distribution in a gravity field. This requeres examining the Newton’s law of gravitation , the gravitational field vector of a limited material distribution in a specific point and po tential function togother with the potential energy. In paper, have proved that potential energy vanished in infinity . This requires also examining Hamilton’s function then we have found the escape velocity of a material point from a sphere’s surface ,when the motion of the material point is vertical , horizontal or oblique . We found the escape velocity for a material point from a disk in the vertical and oblique cases. In paper, we also find out the escape velocity from a ring in both vertical and oblique cases . It is appeared that the escape velocity from the ring identifies with that we get from the sphere case.
In this search, we study the gravitational field engendered by a material segment around itself. In the beginning, we discuss the concept of the gravitational field generated by arbitrary curve. It turns out that this field depends on the concept of linear mass, and is directly relate to the distance of the position, to which we calculate the field from the tangents of curve, and not from the curve itself. Material segment is a special case of material curves, and characterized by the confusability of all its tangents, that allow simplify the calculations, and find a simplified formula of the field. We end our research by comparing the field of material segment, with a field of appropriate circular arc. Contrary to what it is expected, it appear in the end that the field of material segment is inversely proportional to the distance from that segment, and not to the square of distance
The present study aimed at revealing the relationship between problem solving styles, and Personality Disorders among secondary school students. The sample of study consists of 350 students (177 males, 173 females) in some High School Students in Homs City. The researcher has used the following tools: The test of problem solving styles, which the present researcher had designed, And The test of Personality disorders which Mario Rahhal had designed and the present researcher had re-normalized it to High School Students.
This study aimed to identify the relationship between the logical mathematical thinking and the ability to solve mathematical issue to the eighth –grade primary students and to achieve this goal , the researcher applying the test logical mathematic al thinking and test the ability to solve mathematical issue prepared by the researcher reaching study sample (150) students from the eighth grade in the main city of Lattakia . The results showed a strong correlation direct relationship between the scores of students (male\ female) to test the logical mathematical thinking and their scores on the ability to solve mathematical issue where this relationship suggest that the greater the degree of the students in the test of logical thinking increased their scores in the ability to solve Test Sports matter . And because the mathematical proof is a tool for thinking logical sense and flour among students is based on a holistic yiew and a careful analysis of the elements of the issue and then re-installed flexibly . The study suggested the need to develop educational programs that contribute to the development of mathematical reasoning among students , which may help in developing their skills in mathematical proof , and training teachers in the development of logical thinking , and provide the necessary training courses before and during service.
