Research

My recent time is being spent in learning tools and techniques from algebraic and differential topology that can help solve problems in algebraic geometry. Currently, I am interested in the connection between motivic homotopy theory and affine fibration theory. In a broader perspective, this also includes various cohomology theories and birational geometry. From time to time, I also indulge in various texts on physics and psychology. In my Master thesis, I studied the fundamentals of the homotopy theory of schemes and the dichotomous behaviour of vector bundles in algebraic geometry.

$Ant on a Klein bottle$

OK! but what's so special about this bottle? This bottle has no inside or outside and the total volume = Zero! It originally resides in 4-D but when viewed as a 2-D surface, we see an intersection through itself that leaves anyone who travels on it confused. Click here for more interesting facts ;)
