Prove that every subspace T1 space is T1 space/MSc 2nd sem maths/topology #mathematics #theorems

✅ welcome to the maths collection 🎯 Every Subspace of a T₁ Space is T₁ Space | Topology | MSc Mathematics In this video, we prove the important theorem: "Every subspace of a T₁ space is itself a T₁ space." This is one of the fundamental results in General Topology and is very important for MSc Mathematics, NET Mathematics, GATE, SET, PhD Entrance Exams, and university examinations. The proof is explained step by step using the definition of a T₁ (Fréchet) space and the subspace topology. The explanation is designed to help beginners as well as advanced students understand the theorem clearly and develop a strong conceptual foundation in topology. 📚 In this video, you will learn: Definition of a T₁ Space Definition of a Subspace Topology Statement of the theorem Complete mathematical proof Why every singleton remains closed in a subspace Conceptual understanding of hereditary topological properties Exam-oriented explanation with easy steps This theorem is frequently asked in MSc Mathematics exams, CSIR NET, GATE Mathematics, IIT JAM, PhD entrance tests, and various university examinations. If you are preparing for any competitive mathematics exam, this lecture will strengthen your understanding of separation axioms.
