With its emphasis on the argument principle in analysis and topology, this book represents a different approach to the teaching of complex analysis. The three-part treatment provides geometrical insights by covering angles, basic complex analysis, and interactions with plane topology while focusing on the concepts of angle and winding numbers.Part I takes a critical look at the concept of an angle, illustrating that because a nonzero complex number varies continuously, one may select a continuously changing value of its argument. Part II builds upon this material, using the argument and its continuous variation as a tool in further studies and clarifying the complementary aspects of complex analysis and plane topology. Part III explores the link between the two subjects to their mutual benefit. The first two sections are intended for advanced undergraduates and graduate students in mathematics and contain sufficient material for a single course. The final section is geared toward the complex analyst and is intended to provide a foundation for further study.

I liked it
Very firm to be placed on counter top. Baskets have enough space to store onions, fruits etc. Fair price as well.

Better Have Counter Space
Purchased with the idea to reduce counter clutter and have central location of fruits and vegetables.
The idea behind the stacking basket bins is fine, but with limited counter space, it just seems to add to the clutter. I am also only able to use the bottom plate and one basket as stacking height would extend high enough to block cabinet doors. Good idea, but not for those with limited counter space and or lower cabinet clearance. Check measurements and counter space.

Excellent product
I was looking for onion and potato storage and I am very happy to find this. Even though item made with plastic material, it is very sturdy and easy to assemble. I store 3 bags of onions( costco bags) and a potato bag. I have very small and narrow space for onions and potato storage, and this stackable baskets are perfect .

very happy with my purchase

The quality and craftsmanship of this tray are amazing! I bought it mainly for jewelry photography, and the results turned out even better than I expected ✨
The matte finish is exactly what I needed because it doesn’t reflect light, which makes photographing jewelry and pearls so much easier and gives the photos a much more elevated look 📸
I took these photos at night under white lighting, and I’m honestly so happy with how they turned out. The background looks clean, soft, and aesthetic. Sharing some of my photos here for reference — highly recommend!
